Mike,
It's a VFP bug, this works around it:
push menu _Msysmenu && work around for bug in VFP5 KB Article Q164868
report form (this.mcReportForm) preview &lcNowait &lcSummary
pop menu _Msysmenu
>After running a report in Visual Foxpro 5.0 my menu becomes disabled. The menu items are in black (i.e. not greyed out) but none of them work including the exit.
>
>I've recreated this with a simple report and four-line program which runs a simple menu and the report and I still have the problem.
