When I start working on Excel, For 4-5 hours it works well. But after some time when i enter "=" it types '^' and for 'Y' it types 'Z' and many more other shortcuts also get changed. Plz hep me if any one else has experienced the same problem with excel. I am using Dell laptops this problem was there with lattitude 6300 and currently with lattitude 6400. I am using Excel 2000.
