Mouse Up Mouse Down

What do you mean?
Can you give an example of what you are trying to do?

why don you try putting a variable for example "pod" in the declaration part on the form, it can be an boolean

Then in the begining of the mousedown procedure put an if like this:

if pod=true then
exit sub
end if

Now in the beginig of the mouseup put pod=true so whe mousedown procedure try to start it will "exit sub", then is up to you where to enable this procedure again just puting pod=false

I hope this helps you...
