I found, that for my combo class the magical number is 38.

But now I have another weird effect. When I open the form the first time (the form has a pageframe and a container on it) and open the combos for the controls that are in the bottom of the form, the drop-down portion is shown not close to the control, but somewhere... The next time I open that combo the drop-down portion is shown correctly at the top on the combo.

I'm running in VFP8.

I can send you a print screen, if you'd like. What address should I use?
