Victor -
Hello. I'll give that a shot (though I am 98% sure the form's .Theme property is already set to .F.). I don't think it's a form-setting issue... I do think it's a workstation problem... perhaps I've installed some software that clobbered a DLL that VFP needs... something along those lines. These forms have been around forever and never had this problem.
I'll let you know though once I test your suggestions.
Thanks.
