My program has a combo box used to look up a horse by its name. This has been working well for 6 years. An odd symptom has been brought to my attention. It's most repeatable when the horse's name begins with the letter "I". Say I'm looking for a horse named Instant Equity. When I type an "I" in the box, the first horse's name beginning with I appears ("I Dream Of Ivory"). Then when I type the next letter - an "n". On SOME of my client's computers, the "n" will insert between the "I" and the space behind it - making it say "In Dream of Ivory" - instead of picking the first horse name beginning with "In". My Win 7 computer shows this symptom (both with Access 2003 and 2007). The client's server (using Windows Server 2003) does NOT show that symptom (using Access 2003) but two of their Win 7 computers (Access 2003) do show that symptom. Any ideas/suggestions?
