X3 Producer Freezes Up

Hi,
Every time I set up a folder to place common tracks into--say all my drum tracks--the system totally freezes up the second I click on the (-) tab.  All the tracks collapse and apparently go into the folder but I have to restart my computer to be able to use X3.  Sure would appreciate any advice.
Thanks,
Mike

Hey Arlen,
Thanks for the suggestion.  I tried using other templates but no luck.  I downloaded the 60 day free trial of Platinum just to see if the freeze problem is fixed in this version.  No luck there, either (too bad-I planned to immediately buy Platinum if it fixed the problem) .  Then I checked with the tech folks at Sonar and they suggested deleting all my C++ files and reinstalling the C++ files direct from Microsoft.  I did that and.....Sonar still freezes.  There's got to be something that will fix this bug.  If not, I'll just have to live with lot's of visible tracks (suppose I can live with that, but still....).
 
Thanks again,
Mike

Thanks Colin for chiming in.
That was my next suggestion.
