I was not able to replicate with a VMWare machine (40 GB storage). Does the problem only occur with the SSD, or does it happen on other drives as well? Try using "-datadir=D:\bitcointemp" command line option to set the data directory to another drive.
I will try this but unfortunately the problem does not occur consistently. I've seen it twice in two weeks but never before then. Am still hoping that someone else has seen it!
*grins* I hope I am not revealing your prank, but you'll scare the shit out of him when he notices that his wallet is empty when he points to a new (and initially empty) data directory !
Hehe that's a good one. Despite my Jr. Member status I've been around Bitcoin since early 2011 so I'd have not freaked out
