Win 7 Magnifier Propblem

[Elrikk]

Being an older dude with some eyesight problems I run DWU in a 1920x1080 window on my native 1920x1200 monitor.

Then I can activate the Win 7 magnifier with a double middle click.

The problem is that while the double middle click works fine to activate the magnifier it has no effect when trying to exit it and I have to move the mouse to locate the magnifier icon onscreen and then click it and then click close.

This works but is a bit tedious.

Any ideas on what in the DWU program might be eating the double middle click and why only when trying to close magnification.?

I have this same problem in some other games but the double middle click works fine in most.

Any help will be greatly appreciated.
