I've got VFP 5.0

When I use Timer control in a form that already have some combo boxes. And run it, combo boxes become crazy 'cause I can't choose any options. And if i choose one anyway, it behaves as I were clicking behind the dropdown list. non-understandable!

Have VFP 5.0 bugs?
What must I do to get fixes...

TIA 'n Let Jesús fill your souls...
