We have a VFP 6.0 (SP3) compiled app that sometimes (say, once every hundred times) generates error 2028 "API call caused an exception" on a CLOSE ALL command when the application is shutting down. The only API calls in this application are some registry reading/writing functions.

Anybody have a suggestion where to start troubleshooting this? It's not a *big* problem (never happens while people are actually working in the program), just an annoying blemish we'd like to fix and I have no idea where to start.

TIA, Doug
