I am using a combo box that list about 510 items in the drop down list. When I select the 509 items in the list the combo box refresh fine. When I go back and try to select a different item in the list. I get an error. Anything from 1 to items 508 are ok and any items above 509 is ok. So the only item in the drop down list that give me an error every time is 509. Has anyone run across this before and have a work around. I think this is a FoxPro problem. I am running VFP 5.0b.
