Netbeans freezes up on SVN commit: SOLVED

My Netbenas froze up each time I tried to do a SVN commit.
I found the solution here: https://netbeans.org/bugzilla/show_bug.cgi?id=170770

The problem was simple: NetBeans tried to open the commit dialog in some screen location which it can not access (probably because I am switching between different sets of home and office monitors).

So go to the NB-SVN config file and remove the line defining the commit dialog location. In my case the file is located here:

C:\Users\david\AppData\Roaming\NetBeans\7.2.1\config\Preferences\org\netbeans\modules\

Delete the following line:
svn.commit.dialog=2555.0#179.0#607.0#515.0

- and everything is back to work.
