Currently checking with them on their caching method.

Found over 65,000 temp files from the board in the C:\WINDOWS\TEMP folder. I deleted all of them after the drop and re-import and they're now back up to about 800 files and 10MB of space.

I don't mind them creating/using them, but if it uses this many this fast it needs a solid method to do a cleanup of them as well otherwise within a few weeks or less the OS will quit responding as it will be out of space.
