Delay in Outlook 2003 via RDP since IE8 installed

I’ am struggling with the following problem.
Infrastructure: terminal server, Windows Server 2003R3 SP2, Outlook 2003 SP3, IE8
rdp device: thin client, Windows XP embedded, RDP 6.0

problem:
Opening a html e-mail and trying to forward or answer it ends in an
“input-delay” no matter the input is done by mouse or keyboard. But if I take
control of the “delayed” user session from a full XP client the session works
proper! So there is no real delay on the terminal server moreover in data
transfer between terminal server and XPe client.

further details:
The problem does NOT occur when forwarding or answering this type of mail in
a not maximized window!
The problem does NOT occur when IE6 is installed on terminal server instead
of IE8!
And not all html mails are affected!

Also had numerous vbs programs that used SendKeys to open programs and sign on users, they all started failing.  I had to add Sleep commands between subsequent SendKeys to get them to start working again.
Example before install of IE8:
  wscript.sleep 2000
  shell.SendKeys( "+{TAB}" )
  shell.SendKeys( sUserID )
  shell.SendKeys( "{tab}" )
  shell.SendKeys( "{ENTER}" )
now i have to do this:
  wscript.sleep 2000
  shell.SendKeys( "+{TAB}" )
  wscript.sleep 2000
  shell.SendKeys( sUserID )
  shell.SendKeys( "{tab}" )
  wscript.sleep 2000
  shell.SendKeys( "{ENTER}" )

I held off installing IE8 on our terminal servers for as long as I could.

Any help is appreciated.
