Problem was solved by adding this to the init...

Remarks
When the AutoYield property is set to False (.F.), and program code is executing, Window events are placed in a queue. DOEVENTS executes all pending Windows events and processes any user code associated with the Windows events. If no events are in the queue, Visual FoxPro disregards DOEVENTS and continues program execution.

_vfp.AutoYield = .t.
