Created attachment 148252 [details] Bug itself I got issue with tab stripe after IDE restart. Sometimes when i launch IDE, some tabs (usually one or two) can be outside of projet row. As you see on screenshot bug.png after restart, the tab "WebMain" is not in green project row. And sometimes whole project row may change position, for example: first green row, after restart can be in the bottom with different color. I don't know how to reproduce this bug. It happens not often usually on first IDE launch, seems like some sort of race condition or something. --- Product Version: NetBeans IDE Dev (Build nbms-and-javadoc-1931-on-20140722) Java: 1.7.0_51; Java HotSpot(TM) Client VM 24.51-b03 Runtime: Java(TM) SE Runtime Environment 1.7.0_51-b13 System: Windows 8 version 6.2 running on x86; Cp1251; en_US (nb)

I can't reproduce the problem with un-assigned document tab in the same build. The project row position/color may change with the project was renamed or moved to a new location.

And also my pc is not fast, first ide launch takes about 2 minutes, maybe it affects. > The project row position/color may change with the project was renamed or > moved to a new location. I understand, but it changing just after IDE restart. I mean no files was changed or renamed, i just close netbeans and launch it again.
Created attachment 148278 [details] Assign issue More information: See screenshot tabassign.png: 1) I have made first screenshot and exited from netbeans IDE 2) I have run 100% cpu load program (for each 2 cores) and launch netbeans again. As you can see bug was reproduced: 3 un-assigned document tabs on top. 3) I have clicked on first tab (WMain.java) to open document. Tab was activated, document was opened, all fine. 4) I have clicked on second tab (NotifyMgr.java) and as you see, the first tab (WMain.java) was marked by yellow color, so as i understand it was binded with project when tab was activated. 5) I have click on last tab MNotify.java. Same thing document was marked. Then i closed this last tab by clicking on X button. 6) And as you see, all un-assigned tabs was automatically assigned to projects. Tabs was moved into project row. Maybe it because of 100% CPU load and many opened documents, i don't know. I hope this can helps. And sorry for my bad english.
Thanks for the extra info, I tried to fix it in core-main aad489df7bb2
