I create a form in access 2k3 data project connected to sql server 2k5. I put two check boxes on my form. On runtime, when i click on one of check box, it also fires on the other check box...set check box value from false to true. But it works normally when i use keyboard shortcut to fire that check box. Could someone explain this? I run office 2k3 on windows server 2k3 and updated to the latest service packs.
