Chris thx for yr reply.
well, i have a letter that i wrote as label of text box and its very fine
in IE, now i type same letter in text box but it appear as rectangle? And
when i save the data submitted from form into database and retrieve it back
its appearing very fine as label(though it was displayed as rectangle ).
Problem is just when i type in text box? As you said this seems to be
problem with font but why it appears correct as label then?
Also i am using MS San Sarif which is mentioned on XP site to support
Arabic/Urdu characters.
