XP_proof_rus_sp2 with Gw7clientSp1.

GW client configure as:
Tools | Options | Enviroment | Default Actions | File Attachments
(*) Open Attachment

Recieve mail with 2 attachments. (attachments have RUSSIAN NAMES !!! )
Press on the first file.. Exel run.. but not open attachment :(
If i do as:
Highlite Attachment | Right button mouse | Open.. as result - Exel run and
open this attachment.. OK !

If attachment have only english name - all work OK !

What can i do for resolver this problem ?
