the problem still remains. I'm using Win 7 Ult x64 too and just updated to the last version 7.0.5.7 Anytime i'm closing EMM it freezes and does not responding.
I'm now using version 7.0.8.9 on Win 7 home 64bit and I have had this problem almost since I first started using it. I kept hoping the problem would be fixed during one of the updates but with no luck. I just did a fresh install of Win 7 AND eXtreme Movie Manager but the problem is still there. Any help getting rid of this problem would be GREATLY apprectiated...
The problem is that I cannot reproduce it. I have really try everything but in my tests XMM closes correctly without any error message, both in 32 and 64 bit windows.
