Observed in 4.0 (on a friend's machine) and 4.1 (on mine). Open a form and select some bean in Inspector. Make Inspector/Palette windows wider (drag left margin to the left). Click on some other window, or double-click a bean to transfer focus to the editor mode, etc.; the Inspector/Palette mode gets resized back to its original width. Not known to occur with other windows than form editor windows.
Major usability problem for the form editor. I can barely use the Properties or Inspector windows because every time I click on something else, the Palette window reverts to taking up about 80% of vertical space, then about 10% each for Inspector and Properties. Have to resize each window before I want to use it. May be related to a serious problem I also see with refactoring functionality (original description in issue #53440), which is that whenever the Find Usages or Refactoring window opens (at the bottom of the screen), it has no visible height, so needs to be resized using the splitter; and sending focus to any other window sets its height back to zero. Same for Debugger windows, actually. In fact any window other than the Documents area and those windows which I have in sliding mode, are nearly unusable for me at the moment. Moving all the form windows to the left side of the screen (where I have no sliding windows) seems to improve things - they still resize a bit when I change focus, but now the "sticky" values are usable. Does not work for Find Usages/Refactoring at all since there is no way to permanently set a location for these - each window is created from scratch and placed at the bottom edge (with zero height).

The zero-height F.U. window problem disappeared after I deleted my Windows2Local and restarted the IDE.

I noticed the problem with the Form windows too. Having Navigator docked on the right side of the editor seemed to make things even worse. Very annoying.
it's the never ending story with the nested splitpanes. I'll try do my best but the whole concept is generally broken IMO.
reassigning to standa, who is developing a new component that should replace the netste splitpanes nightmare.

there's no good fix for this problem short of rewriting the nested split panes from scratch. this fix solves the problem with nested panes collapsing to zero size (e.g. the attached windows2local) but there are still some split pane configurations where the split bar will jump back after being moved.

This bug is not fixed. I am able to reproduce the bug and the result is that the form editor is virtually unusable. Steps to reproduce: 0) Start NetBeans with an empty user directory. 1) Close the following windows: Welcome, Runtime, Files (by clicking on the X button in the window titles). 2) Open NetBeans module debuggerjpda/ui (without "required projects"). 3) In the Projects window, expand the project's root node and the Source Packages node in it. 4) Resize the Projects window - make it wider. 5) Expand package node "org.netbeans.modules.debugger.jpda.ui.breakpoints". 6) Double-click on node "ActionsPanel.java". 7) Close the following windows: Inspector, Palette (by clicking on the X button in the window titles). 8) Make the following windows sliding: Projects, Navigator (by clicking on the auto-hide buttons in the window titles). 9) Click somewhere in the Properties window (currently empty). 10) Click somewhere in the form. 11) Click on the title of the Properties window. 12) Click somewhere in the form. 13) Widen the Properties window, so that all three buttons Properties, Events and Code are displayed in a single row. 14) In the Properties window, click on the name of property "enabled". The Properties window shrinks so that it is very narrow or even invisible. Try to resize the Properties window in order to make it usable again and click on the form. The Properties window shrinks again! The form editor is virtually unusable.

this used to work but because of issue 55519 the problem is back. i suggest to roll the fix for 55519 back. imho it's better to have editor pane that doesn't fill remaining space correctly than having properties panel shrinking to zero width. any comments milos?
fixed i rolled the fix for issue #55519 back and reopened that issue instead. Checking in windows/src/org/netbeans/core/windows/view/ViewHelper.java; /cvs/core/windows/src/org/netbeans/core/windows/view/ViewHelper.java,v <-- ViewHelper.java new revision: 1.14; previous revision: 1.13 done
Ran into this problem today on version 4.0 under Windows XP and don't know why it was working ok before. Found workaround 1. Press and hold CTRL key 2. Move mouse over splitpane bar until left-right sizing arrow appears 3. Press left mouse button and drag to new size 4. Release mouse button 5. Release CTRL key The splitpane is no longer a splitpain.
closed, wasn't reopened for a long period of time.
