[dba-VB] Thread.sleep

Garbage Collection, although I think you are being facetious. :)


You have stirred up in my head regarding a project that I have out there
that seems to cause memory issues on certain computers.

I haven't been able to recreate this in my office.

I do use sleep as well in several places in that app.

Care to share the code that worked for you?

Thanks,
David
