"Ease of Access - Make the Mouse Easier to Use" will not turn off Auto-maximize

Question

I have a dual monitor setup and any window that I drag over to the right hand monitor gets auto-maximized. A red border appears around that monitor when I position a window (any window) in it. The left hand monitor works normally. I can make the window smaller,
but if I try to move it from the top of the monitor or from the left side then it auto-maximizes.
This problem does not occur if I log onto my wife's user account, so it must be something in the settings for my account.
I see many people asking how to turn off the snap feature, and I have checked the "Prevent Windows from being automatically arranged..." box in the "Ease of Access" item in the control panel" - but this does not fix the problem.
My tale of woe seems a bit different than what I have seen described in various forums.
Has anyone seen this problem and solved it?

Hi,
Here's the way to disable auto-maximize via the registry:
1.Run Registry Editor (RegEdit).
2.Navigate to the following registry key:
HKEY_CURRENT_USER\Control Panel\Desktop\WindowArrangementActive
3.In the right-pane, double click (or right click and select Modify) on WindowArrangementActive, and set its REG_SZ value to 0 to disable ; 1 to enable.
4.Close Registry Editor.
5.Log off and log on again, or restart computer for the change to take effect.
Hope it helps.
