Ok, you want to keep the form with Button1 to stay open all the time, 
and you want to be able to access the Main form at the same time? Then 
you should use Show instead of ShowModal.

ShowModal is for opening forms which must have the user's attention and 
a "Close" or "Cancel" button to close them PRIOR TO be able to access 
the calling form again. It will pass a Value to the Close event, so the 
calling form can read what happened in the meantime. (Personally, I 
prefer to use a number of public variables for this, but it's a matter 
of taste...)
