Good news. I kept a game open to full screen for that last 45 minutes and it did not minimize while version 72043 was installed. My computer is pristine in all regards so this was baffling to say the least but the newest version has resolved the issue.
I am going to pass along to other readers that using Thunderbird can cause a full screen app/program to minimize. I never got that problem worked out so I switched to eM Client (POP3 Gmail/Comcast). Still use it on Windows 7 because it’s a clean Interface and it does not steal focus when checking email server for new mail or when it’s mimized to System Tray or Taskbar. WLM2009/2012 work well too for hotmail, outlook, msn and live accounts.
The worst thing (other than a disonnect) for gamer is to have the full screen program minimize in the middle of your entertainment.
I give my stamp of approval to Mike for a great System Tray (cursor hover) weather watcher.
