Hello Walter.

So far, I was not able to reproduce the problem in a simple case.

That is unfortunate. If you can't reproduce it, you can't fix it.

but my experience in using grids and comboboxes says you don't want to use too many tricks.

I, OTOH, have done some really fabcy things with combos in grids. Sometimes it has been a lot of work, but the results have been worth it.

but my experience with grids (that might exceed even yours (see the 10 or so grid bugs in VFP 8 I've submitted))

I always thought that experience was measured by the number of successful applications one had delivered < s >.

say you want to keep it simple if you can.

That is true for all parts of an application, not only grids.
