Eeeee. I hate to say it, but basically you need to dump the combo box IMHO.

#1. combos have a nasty 254 (255th?) element bug for cursor rowsource cbos.
#2. They are verrrrrrrry slow in grids. I couldn't even deal with a 100 item combo list.
#3. Ick! < s >

The standard solution I've read here and other places has been working well for me, tho' I resisted it for a long time. Use grids for displaying info and use controls outside of the grid for actual editing.

The time I save in mucking about with grids and cbo is well worth it. Plus I sleep better at night!

Good luck.
