This submission [Magnifier quits when IntelliPoint/IntelliType is installed] has been removed because
IntelliPoint is not part of Windows, sorry.
While either Intellipoint or IntelliType is installed, "Magnifier" will quit unexpectedly if any mouse button is clicked.
Note mentioning is that it doesn't crash, as it displays the shutting-down animation and everything.
Also, the "+" and "-" icons on the magnifier toolbar seem to be immune of this.
Completely uninstalling both IntelliType and IntlliPoint seems to solve it, but that's hardly a solution
New version available from Microsoft that fixes this issue
