hmm, I just tried this and it works just fine for me...
specifically,
1) created a form in VFP6
2) added a combobox with 3 columns and put long strings in each
3) set the columncount to 3
4) set the columnwidths to fit the long strings
5) put copies of the combo at different places on the form, to see if it extended past right and left sides

ran it in vfp6 and vfp7 and it worked the same in each. extended past the form, left and right; showed all 3 columns

if you set the combo to have RowSourceType=0 and use AddItem() and AddListItem() to add items, do you still have the same problem?
how about on a form created directly in VFP7?

SWAG: i wonder if this is an OS issue? what OS did you see this under? do you have other machines with different OS's you can see it under?
