Use doevents to prevent hanging your system....

but use statics in your code to flag if the procces is already running
like this for a command button:


Code
-------------------
Static boolean AlreadyClicked

if Not Alreadyclicked
AlreadyClicked = true
'Do Your Stuff
Doevents
'do more stuff
Alreadyclicked = false
end i
