This is a hard problem to describe: Sometimes as my mouse pointer is moving
over a list of selectable items (like a pull down menu or after if right
clicked) the mouse will automatically select an item even though I did not
left click. This is extremely frustrating because I work with spreadsheets
quite a bit. After I've highligted a formula or other cell contents to
change the properties (cut/paste, change format etc). I'll right click to
find the appropriate action. As I'm moving the mouse to the appropriate
link, the mouse will randomly activate an action. Again, I haven't left
clicked to select it.

Does anyone have any idea what causes this? It's driving me crazy.
