Ok this is my first post on this forum , bear with me please.
This is for my parents computer it is an older model of toshiba, satelllite ... something 5-6 yrs old. Windows 98 se. Nothing wrong with their computer until I installed a Microsoft Optical wheel mouse and its software onto their computer.
Now the "?" is an e with a dash over top of it and the "shift" has the same problem.
Also the optical mouse works fine in the USB port but when you move it to the mouse port it goes haywire. It goes crazy as well, if its in the USB and you touch the "little green pointer thing in the middle of the key board" um yeah ;) lol)
I also changed the language settings from American english to Canadian english.
Not sure if that had anything to do with it.
However the fact is, before I installed the new mouse and mouse software the keyboard worked fine, and after I "messed" with their computer the keyboard is screwed up.
