How do i now get this window refreshed? This is happening very often now with 201202xxxx build release. Not with the old version.
The IDE completely getting freezes and i have no way to get it refreshed unless i kill and lose my source code.
Is there any better way to get it resolved? (everyday at-least 2/3 times it occurs).
That is a development build of netbeans. It is quite possible that bugs have been introduced in development builds, but not fixed. I would suggest using the most recent stable release, which is 7.1.
