I bought a brand new Dell Inspiron laptop running Windows 8. This has a mouse touchpad, not a touchscreen.
When we are using the laptop and are moving the mouse around, the Windows Charms sidebar will often pop up unexpectedly and interfere with our work. How can we stop the Windows Charms bar from popping up unexpectedly?
According to the Windows 8 documentation, the Charms bar should only display when I move the mouse pointer into the upper-right or lower-right corner of the screen, or when the user types 'Windows-C'. I assure you, our mouse is nowhere near the corners of the screen. Nor are we hitting 'Windows-C'. Usually I am moving the mouse pointer around in the middle of the screen, and suddenly for no obvious reason, the Windows Charm bar appears for no reason.
It is not something that I can replicate. I've tried various touch gestures and I have not been able to replicate this problem.
I disabled particular mouse gestures as suggested below, and this worked for me. I updated the trackpad software, which re-enabled the mouse gestures and reinstated this obnoxious behavior. I had to disable it again.
