Thanks for those inputs (you and Naomi)... However, I've already done the debugger, step into, looked at the stack, but NOTHING shows... The code fails explicitly at Thisform.Refresh() and since there is no code in the class definition (nor parent level going up), it just errors out. Won't tell you which control it was in the middle of when it errored out.

Yes, Naomi, the comboboxes were the suspected culprits and I have advised him on looking at that AND the grids (in case any REQUERY() being done) and grids getting hung.
