Try this: Click start menu>Search 'Programs and features'>click 'turn windows features on or off>scroll down and uncheck 'Tablet PC components. This is what I do when I first install my Wacom drivers on windows 7. If the problem is still present, then this may work. Go to control panel>hardware and sound>pen and touch>double click press and hold> uncheck enable press and hold for right clicking box.
No no. Once you did the first step, for the changes to take effect your computer needed to be turned off then back on.(which I'm sure has already been done, by now.) the second one(that resolved your problem) didn't need for you to restart for the changed to take place. The problem wont come back unless you undo what you did last night. Sorry for the confusion~
