I'm having a problem with a combobox dropdown. The source for the combobox is an alias. In the dropdown event I set a filter on the alias that is the source of the dropdown. The default Displaycount is 15. When the dropdown happens the first time, there are 15 rows in the dropdown, regardless of the actual number of rows to display. If there are less than 15, the remainder of the dropdown is blank. On the next drop down, there are only the number of rows as there was data in the prior dropdown.

Example.

In the first dropdown, there are only 10 items that match the filter. There displays room for 15 rows, where the last five are blank space. I then change the filter. On the second dropdown, there are 30 records that meet the filter. The dropdown will be 10 rows. There are no scroll bars, only an arrow down in the last row of the dropdown. If I close the dropdown and then just dropdown again without changing the filter, there are 15 rows and scroll bars as expected.

VFP8 with SP1, but the same problem occurs in VFP6
