Windows 7 explorer run prompt window position on screen varies

Question

whether I use the mouse via start/run or <windows key>+R the small window that appears to await input from me for the run command line dpes not consistently appear in the lower left above the windows start globe (forgive inaccurate nomenclature). 
Generally speaking, say 50% of the time, the machine; a dual xeon HP z820 with AMD Firepro graphics and 3 display port NEC monitors with the AMD/ATI current catalyst pro drivers and NEC spectraview 2 running, puts the run window immediately above
the start globe.  but the other half or more of the time it could be dead center in the active monitor or at varied locations about the center of the active monitor (reported as #2 in the Microsoft ID monitors results).  It's never been on a non
primary monitor and I've tried switching monitors. to change the active one, and I've tried switching between and deleting the profiles for eyefinity, which btw is rarely in use.  It's generally just in the extended windows mode with 3 monitors.
Is there a way to correct, control, or otherwise manage the location of the run prompt window?
thanks in advance,
fw

I came here looking for a solution to a similiar issue where the "RUN" dialog kept popping up in the middle of my screen.  This thread helped me find the answer even though the answer was not in this thread. I thought I post what actually fixed my issue.
AMD graphics have a feature in AMD Catalyst Control Center.  Look for a setting called "Dialog Control \ Enable Dialog Repositioning"  it is enabled by default and makes your dialogs go to the center of your primary screen.  Disable it and
everything goes back to normal.
