I have trouble logging out after installing nis2009 in XP

My PC was working just fine until a few days ago, when I had trouble logging out of XP.after re-installed nis 2009.

 

What happens is that the process window hangs for 30 seconds or so with a ctfmon.exe process that wont close.

does anyone know what could be the problem? everything else works fine.

 

I don't want to go to 2010 just yet - if it works why fix it?

 

tnx
