[imp] charset problems

[Ilya]

I receive emails written in cyrillic:
"Content-Transfer-Encoding: 8bit
Content-Type: Text/Plain;
  charset="windows-1251"

however when i open them in IMP (inside the frame) all letters are shown as
question marks. Same thing happens when i open it in new window (shift click).
But if i open message source the letters are correctly presented. I just updated
to latest CVS of everything to insure its not a known bug.

does anyone has any ideas how to fix this?

thx a lot!
