It could be that the code in the event handler is taking a long time to complete, which means Win32::GUI won't have a chance to update the GUI, and the program will appear to hang. This includes redrawing controls. So if a lengthy piece of code is executed when a button is pressed, it will remain pressed until the code returns to the dialog loop. One solution to this problem is to periodically call Win32::GUI::DoEvents() in your code to allow Win32::GUI to process any pending events. Example:

sub Button_Click {
    while(1){
        # do something...
        Win32::GUI::DoEvents();
    }
    return 1;
}
