I have a friend who is using windows and has a bilingual english/thai keyboard. She has lost the ability to enter text in thai in the text fields and search boxes IN websites. In the IE address bars and the yahoo and google search bars she can enter text in thai or english by switching the language setting in windows but in the websites themselves, e.g., google's search window at their website, switching to window's thai language settings do not work (used to be setting ALL CAPS down).

Is there a windows setting or is it a google preference setting that needs to be changed?

Thanks.

Is she using a non-Thai version of windows? You didn't state the operating system, but this guide is for XP:

XP should provide the ability to add language options for input and seeing returned Thai. If you go to the Control Panel you should see a choice for "regional and language options" or "date, time, language and regional options."

Once you make it to the proper dialog box, you will see a tab for "languages" where you can add the files necesary to support "complex script" languages, afterwards being able to add the keyboard files for Thai. Switching between Thai and native keyboards is a user selectable key combination.

Similar options for Vista.
