I had been successfully forcing Blue Iris Pro to open in monitor #3 (at bootup) of my triplehead setup, which is using Eyefinity (so MS Flight Simulator X can easily span all 3 displays) for several weeks. But now, after recent updates to both Blue Iris Pro and to Display Fusion, Blue Iris Pro ignores the Window Position rule (I even tried deleting and making a new rule) and always opens in monitor 2 (the center, with the task bar) as Windows 7x64 Home Premium starts up.

I noticed there is a checkbox for forcing the program to open on the same monitor as the taskbar, but that is unchecked. 2 other programs are still properly opening on their assigned monitors. I've had no luck figuring this out.

Blue Iris Support says they don't know why this might be happening.

Currently I have a shortcut to its executable stored in the Windows 7 Startup folder. What is frustrating is that it will open on the specified monitor if I am already running Windows and close Blue Iris, and then open it from the start menu. Whatever is going on must be related to the boot process. I wonder if something like Startup Delayer would be helpful? I've used that in the past for some USB stuff when Windows was not recognizing it during boot up.

Edit - OK, I just set up Startup Delayer to make Blue Iris wait until the CPU is 60% free. And that seems to have solved the problem. On a reboot, Blue Iris opened in monitor 2, and then jumped over to monitor 3 where it is supposed to be. I can live with that.

I am guessing Blue Iris gets up and running before Display Fusion is running, during the boot cycle, and that is why this was happening.

Thanks for the help.
