Programs that do not check to see what the Windows setting for decimal and thousand symbols are often will behave strangely. Many countries use the continental European system, where there is a decimal comma and a point (dot) every three digits starting with 1,000. The English language, of course, uses the decimal point and the thousand comma.
A well-programmed Windows application will check to see what setting is active. However, if your program doesn't do that and you're going to work with it for more than a minute or two, you can temporarily change the setting. If you're working with an English or German version of Windows, it goes as follows. If you have a different international version, you'll have to find your own vocabulary.
English Windows 7:
1. Open the control panel.
2. Pick Region and Language
3. Click the radio button Additional Settings
4. Change the settings
German Windows 7:
1. Systemsteuerung Ã¶ffnen,
2. Die Option Region und Sprache wÃ¤hlen.
3. Den Schalter Weitere Einstellungen anklicken.
4. Die Einstellungen Ã¤ndern.
You can use similar paths with Windows Vista and Windows XP.
Also important; If you're using the Ultimate version of Windows 7, you can change your Windows language at will. I, for instance, have the German version of Windows, but I often run it in English mode, which gives me the same basic surface as the U.S. version. However, switching languages will not switch the decimal comma-point settings! That still needs to be done manually.
The decimal comma-point issue probably is the reason I never could get the thing to work. See my earlier posting above. I never tried changing the decimal point-comma system.
