Description madiot 2007-09-25 09:29:21 UTC 
open 5/10 java files from a java project containing about 150 files.
try to shuffle the tabs, getting the orange outline of the tab is already slow to appear
and moving it to desired location is both slow and imprecise.

i always had this problem for as far as netbeans 4, but now testing in 6beta would have thought something should be done
to address this.

btw, i noticed that even resizing of the main nb window isn't very smooth either. perhaps it's a general apple jdk issue.

Description:
- we need to check glass pane handling, either remove it completely or use faster technique
- consider to get rid of JDK DnD support, we don't need to move windows to other applications, perhaps just checking
user gesture for drag start and tracking movement will be cheaper

Time estimation: 3 man weeks if we decide to rewrite DnD support
