This worries me about FFXIV:ARR being able to cooperate with other programs on the Windows PC. I have a program called Pop Peeper that notifies me when I have an e-mail and when it does notify me while FFXIV:ARR is running, the HUD for FFXIV:ARR will start flashing and will not stop till I exit Pop Peeper. In addition to having to exit Pop Peeper, if exit while the HUD is gone, it stays that way till I restart FFXIV:ARR client.

Please watch this youtube video for example of bug.
