In a VBA app for Excel, I have a form with an EVENT button that starts a timing routine using the function Timer.  Works great, except for the fact that clicking on EVENT to start the next cycle takes nearly a half second before the cycle starts.  Is that normal? It may not matter in the end because it will be triggered by software, but a human trigger and the button has a delay.  Can I shorten that delay?

Side comment, I have noticed that in XP the smallest Timer tick is 1/64 second but in Vista it is 1/256 second! (Office 2003 Excel)
