Thanks for the update Mark.  I'm glad it's working faster now, but I'm 
not sure why.  I don't recall anyone complaining about performance of 
2.1.x on Win7-64bit on the list before now.  Are you interested in 
downgrading to 2.1.x on one of those machines to see if the performance 
problem re-occurs?
