problems with Lyx multi-language document under Windows

[Ludek Borovansky]

Hi all,

I have a problem with Lyx 1.4.4 under Windows (and Miktex) writing multi 
language documents. I  have my document set up as Deutsch, but I need 
from time to time to type in a Russian language  for example.But when I 
change a language via menu Edit/Text Style and also I change keyboard 
layout under windows, I am able to write in Russian only when there is 
no other language on the same line in the document. If there is for 
example a text in Deutsch at the beginning of the  line and then I try 
to type something in Cyrillic, I get error when trying to view document 
as a PDF file. It says something like:
Missing $ inserted - " ...\foreignlanguage{russian}{45Ů×ÁĐŮ×ÁĐÁ×ĐÁ×}" 
and Latex error: command \DH unavailable in encoding T2A etc.

This error is not showing up if I write only Russian document  or  if  I 
keep  different languages on separate lines (not mixing languages on the 
same lines of text).

I have babel installed and enabled, also I have tried to switch to 1.5 
beta 3 version of Lyx where I don't have this problem, but unfortunately 
this  version is not stable  for me yet and it keeps crashing now and then.


Any help would be appreciated, I like Lyx and its layout of documents 
very much.
