Thanks for all the help with the combo boxes -- it works great!
I have an app that using a timer control I simulate a loop. The loop, using a windows api calls Carbon Copy 32 to initiate file transfers. I need to find a way to break the app out of the loop to it's 'paused' state. (When the timer is counting.) I would like this to be done with a command button to keep the user interface simple for the not so intelligent user. Any ideas?

Thanks in advance...
