[imp] attachments problems on terminal server

[alois blasbichler]

Hello list

I have seen a strange behaviour with IMP (Horde: 3.1.3 mp: H3 (4.2-cvs) )
All works fine if i login from a Pc.
But when i login to Imp  with IE from a terminal server (windows 2003)  
  i dont can open attachments (pdf, tiff) directly - i have to save it  
to disk and then i can it open.

Is this a problem of my terminal server ?

Somebody have seen the same problem and have a quick solution ?

Thank you and by
luis
