I've got Windows XP running with an NVIDIA GeForce 9400GT (with two monitors) and a DisplayLink adapter for a total of three monitors.
During each reboot the third (DisplayLink) monitor changes its position to the far right monitor. I actually want it located under the first monitor to the left slightly (-504,1028)
After each boot its position moves to (2960,536). This is a real pain, and I either need to run some software to move it back, or find a way to get Windows to keep those settings.
I've updated this question to describe it a little better with pictures. I also found a similar post here, but it was Vista, and solved when they upgraded to Windows 7. I can't upgrade.
This is what the desktop arrangement looks like after I reboot.
I then have to fix it and move the #2 monitor to this bottom left location. Upon rebooting, it returns to the first arrangement.
