Some time ago, the edit worked, but the combobox did not. It did appear, 
but when it disappeared it was gone for good. The window handle was 
destroyed and it did not come back. I changed the parent of the combobox 
to be the grid itself and that worked nicely, so I thought: why would 
you not want it like this. However: with current cvs it does seem to 
work; the combobox does appear, and keeps doing so, so it probably was 
another bug.
