When you have a few editor windows open, and you try to use the editor navigator you will see a white box follow the mouse. This does not happen when you first open the iDE. I do not know what makes this happen, I just know it happens after using the IDE for a while.

JDK version / NB build number ?
java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-154) Java HotSpot(TM) Client VM (build 1.5.0_07-87, mixed mode, sharing)
I received similar report in the past AFAIK, however it's quite random and I can't fix without reproducible case, unfortunately...
If you use a Mac for about 10 to 15 mins this will happen. This is very repeatable, you just have to use the IDE for a little while. It does not happen until you use the IDE for at least a little while and you have aout 7 or 8 files open.
Hmm, still not enough reproduction info to debug and fix this tricky bug.

This was 100% reproducible until you requested steps to reproduce. Every time I had used the menu it failed. I just tried it on an IDE that had been idle over night and it is working well now, even though it failed last night. I may have closed it and reopened it near the end of my working session last night however. I would say I generally use the menu when there are too many files opened to see them all in tab titles, and usually that means there are files off both ends of the list. However artificially creating this did not work. It may be that modified files must be off screen, or something of the sort. I will keep an eye on it, and add details as it reoccurs. java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-164) Java HotSpot(TM) Client VM (build 1.5.0_07-87, mixed mode, sharing)
I'm making this duplicate of 101877, which contains some reproduction steps. *** This issue has been marked as a duplicate of 101877 ***
