I'm creating a program that will take credit card swipe from a USB swiper or the credit card info can be entered manually. I've got a loop currently to read the credit card data being entered from a swiper and I have some buttons on the bottom of the window that the user can press to bring up fields to enter the credit card info into manually (ie card number, expiration date, etc). The problem is that while I'm looping to look for the credit card swipe I cannot accept the user's mouse click on the buttons. Has anyone every done this before/any ideas as how to do it?
Current code:
