Description muellermi 2013-09-25 06:29:14 UTC
Product Version = NetBeans IDE Dev (Build 201309240002)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.7.0_40
Runtime = Java HotSpot(TM) 64-Bit Server VM 24.0-b56

whole between two entries. It seems the distance is calculated false (no file missing in between)
see attached pic.

After collapsing and expanding the view is restored correct.

Can you please clarify, which JDK version do you use?
And provide messages.log file?

If you use JDK 1.7.0_40, this is most probably NOT a duplicate of issue #237105, where JDK 1.7.0_25 was used.

Comment 6 muellermi 2014-05-15 06:32:14 UTC
This problem is independent of a special JDK (I'm currently using Java 8 with NB 8)

But, I guess, I'm able to reproduce it:

- open NB on a PC with high resolution monitor
- access this pc via remote desktop from a machine whose screen has a lower resolution and take the running session
- go back to your pc, loginto the existing session

--> NB displays "holes" in the project tree
Theses holes remain, even though you may collapse or expand the tree, until NB is restarted
