Friends, I am really desperate and I hope you can help me. I coded my first GUI script to send free SMS. Description: When $Button1 is pressed the main function starts. It takes about 2 minutes to complete because it loads few web pages and insert some data as logon credentials, recipient number and text message itself. 1. When the button is pressed the GUI is "frozen" until main function is completed. Is it possible to return the control to GUI and press the same button or other buttons t
