Works everywhere, in Word, excel, Outlook etc, just not in the text part of an e-mail in Windows Live.

To enter the text I have to use the TAB button, cant use enter key. It seems strange. Maybe I pressed a wrong key. I am not sure.

Does anyone meet such a strange problem? Hope somebody can help me. THANKS.

Very strange. I would go into the Control Panel, Mouse settings to see if there is a problem there. Some mouse S/W (Logitech for one) have specialized S/W that changes for different apps. Perhaps this is part of your problem????

Is there anything wrong with mouse settings? If no, have you changed any setting of windows live? Try to check the windows setting if what Ted said does not work. Good luck!
