User Comments:
christiaensm: I am editing a C++ class.  I cloned the window I'm working in to have a better overview and am editing in both of them.  I think I've undone some of my editing.  After that, I could no longer see my edits in one of the windows.  Looking at the tab-label of the broken window, you see that the window is still registering my changes somehow but they get lost.

webfox: now I tried to format this 4620 lines, and this error pops up endless no way to stop it. Will resatrt Netbeans beta if it not stops in 5 minutes.

jiriprox: AIOOBE when editing source. (line wrapping was enabled, on save reformat too)

GUEST: Editing text inside of javascript in PHP file

GUEST: rolled back history, copied and then forward again
