Suggestions:
-stuck left arrow key or Ctrl/right shift keys (ie: faulty keyboard)? Try another keyboard.
--There are reports of a Java applet in FireFox causing this problem; are you using FF as a browser? Kill FF in the Task Manager (Ctrl-Alt-Del), and then install the latest version of Java.
--It may help to disable right to left language options (ie: Arabic, Hebrew) In Windows XP's Control panel, open Date, Time, Language and Regional Options, choose Add Other Languages>Details. Add English (US) if it's not on the list. Click on a language(s) you want to delete then the Remove button.
In some cases, you should be able to correct backwards typing by holding down the Ctrl-left shift keys.
