>>Obviously, I can solve my issue by removing the WAIT WINDOW, but I'd really like to understand what's going on. Beyond that, this is embedded deep inside an application in the process of conversion from FPW to VFP, and it uses WAIT WINDOWs extensively to communicate with users, so removing this particular message is a UI issue (and replacing all WAIT WINDOWs with a combination of status bar messages and messageboxes is a non-starter at this time).

Nope, simple string.

The good news is that I learned from the client that they don't actually care about the WAIT WINDOW, so getting rid of it is an acceptable solution.
