Getting control of a form with app running

[borgunit]

I am creating a batch processing routine. The routine does what I want it to, except I cannot interact with the original form while the called application is running. The routine runs like this...

-The program starts
-The form window is shown
-I browse and fill a file list on form
-I set the settings on form
-Start Processing from command button on form
-Another app starts
-Make app visible
-Process files one by one
-(I would like to interact with my form but I am unable to)
-App completes processing
-App closes
-Control returns to form

I would like to enable a command button to minimize the form in another size while the files are processing. The button work but not while the app is running. Any suggestions?

I fixed it with some well placed DoEvents. Thanks anyway.
