you have just installed, you need all your updates as there were fixes for this in the updates. All the way to SP2. If you have, try going to START\RUN..type in Ctfmon.exe and click ok. Then try the ALT\SHIFT.
I used to be able to set up my system to write in Greek easily. I re-installed windows recently and since then I can't set it up again, even though I follow the same procedure I used to. Here is that procedure:
Regional and Language Options
After this, I could switch between English and Greek by pressing Alt-Shift. Now it doesn't work.
There also used to be a Language Toolbar on the Taskbar which is no longer there. I can't find a way to put it there.
Any ideas on how I can make this work?
