I'm all for people being paid for their programming efforts but I had run the software for all of about 10 minutes and had received roughly half a dozen reminders to register the program. During the reminder, which couldn't be cleared, the program is inaccessible. If you want people to actually evaluate your program, turn off the friggin' reminders except for start-up and/or quit. Otherwise, let people use the program and decide if they want to purchase. As it is, I've decided to go elsewhere.
