Ha ha ha!!! AT LAST!
Jim, I had the same problem of refreshrate automatically changing to 75 on my monitor everytime I used any DirectX accelerated software. I couldn't find a solution with anything. I knew it was directX but couldn't find dxdiag in WinXP's DirectX folder and never thought of just using the Start --> Run function to run it.
I posted on this forum but no one knew how to help... I guess you haven't read that post (i was a couple of months ago).
Now it solved the problem! THANKS!!!
Great new version and an old anoying problem fixed in one day!!! You are good
