Product Version = NetBeans IDE 7.2 (Build 201207171143)
Operating System = Mac OS X version 10.8.1 running on x86_64

Runtime = Java HotSpot(TM) 64-Bit Server VM 23.1-b03
This may be the same issue as Bug 214005.
When editing a Java project with a large number of files, sometimes when there are nodes open that extend below the bottom of the Projects panel, it is not possible to scroll to see the bottom nodes - the scroll bar immediately jumps back to a higher position. Sometimes, changing to a different "View Java Packages As..." setting temporarily cures the problem, but at other times, only restarting Netbeans cures it.
Swing and moreover on Mac, Stando please help me.
