Thinapp'd Microsoft Office 2010 not closing all processes

I posted this on the VMware Thinapp Blog  but I wanted to make sure the VMware discussions had it as well.

I've virtualized Office 2010 with Thinapp 4.6 and all the applications seem to run "buglessly" however xxx.dat remains open in memory after closing out of everything (Office 2010).  I've added the VBscript to close xxx.dat on LASTPROCESSEXIT but the process continues to run in memory.

The VBscript works flawlessly on other Thinapp'd packages I've created.  See below:

Any suggestions?
