Yes, now I'm sure that's the problem. On my U.S. English computer, if I enter 10,58 it gets changed to 1,058.00. So if you enter 10.58 on a computer that has the period and comma reversed, it's going to become 1.058,00, which is exactly the behavior that fa123 is experiencing. But it seems like fa123's problem is not quite as simple as having a European numeric format setting. In his screen shots, the numbers are displayed with the U.S. usage. But when he types a period, it's being interpreted as a grouping character, not as a decimal point. Maybe he'll find something out of whack in one of the "additional settings" or one of the other settings that I asked him to check.
