If I did, I would have certianly provided you with them! I'm trying to rule out the physical keyboard hardware.
Okay then, let's try the "On-Screen Keybord"
To do this simply click on the
orb and enter "osk" into the search box. Press enter. An onscreen keyboard should appear. Now use the pointer to click into an area that you can type in such as notepad page or the area in this very window where you enter text to post to the Seven Forums. The cursor should be blinking like normal in the area now. Use the pointer to click the key(s) on the on screen keyboard , which are giving you a problem. Does it correct the problem?
