I certainly do not have the issue that you report "7 out of 10 times, when I touch my mouse, no matter where the cursor is at that moment, the charms activate", for me the Charms only display when I purposely activate them. I wonder what program you are using when you have this issue.
It happens in every program, and on the internet. I don't have a touch screen setup.
I was at a large dinner last night, and found myself near several IT people, ALL of whom have been experiencing the same thing on their own new laptops, and NONE of whom have been able to get rid of the Demon Charms, or even slow them down.
I DID find one thing we had in common. We all loved the new "Chicklet" tablet keys on the new Lenovo laptops, and we all bought one. They're wonderful to type on (especially for me; I'm an author).
Is this issue common only to them? I don't know, but I seriously doubt it. And I know I'm not alone, because there are many links telling how to to make registry changes to solve the problem. Unfortunately, so far, none of them work.
I've double-checked the Regedit changes I made, and they're still in effect, but at the same time, they have no effect.
And it's closer to 8 or 9 out of ten times that it happens. I've gotten very, very good at using only keystrokes, to avoid the dreaded Demon Charms.
