[AccessD] VM dead slow after Accuzip

I run Accuzip (address validation software) in a VMWare virtual machine.  There are two different 
problems I am encountering.

The first is that if Accuzip is still running after the validation (and it is unless I specifically 
shut it down) I can copy but cannot delete the output files.  Shutting down Accuzip causes the 
delete to work (after I copy them off of the VM).  My guess is this is an issue specifically with 
Accuzip, not releasing a pointer to the output files or something like that.

The other problem OTOH is that the copy to another machine (even if Accuzip is closed) is dog slow, 
the "time remaining" literally climbs up to 200 minutes and then stops even telling me how long.  If 
I shut down the VM and restart it, I can do normal and very fast copies.

Does anyone here know how to see what a bottleneck like this might be?  Has anyone ever experienced 
extremely slow copies to/from a vm that was "fixed" by restarting the VM?
