Hello SunRay-Users,

  While using Sun Rays to access a Windows environment we have
  encountered a nasty feature: if there's an application which
  has a lot of screen updates, the session effectively locks up
  until that app has finished its business. There doesn't seem
  to be a reasonable way to break it.

  Example: we use ssh (Secure Shell 3.2.9 by www.ssh.com to be
  exact, but a similar effect happens with Windows telnet, cmd,
  etc.). We log in to a system and `ls` some large directory.
  Or run `configure` or `make` on a project. There's a lot of
  lines of text to paint, and until they are all rendered, we
  can't do much with the RDP client (the whole user session in
  effect). Sending Ctrl+C doesn't help (it seems to lose its
  special priority), we can't minimize the ssh console window
  (unless we prepend `make` with a `sleep`). If we do manage to
  minimize it, there's no such lag.

  We had similar problems with MSTSC, an RDP client from Windows
  2000, but it only occurred on very large-and-fast screen flushes
  and we were usually able to minimise the ssh console, and/or the
  Ctrl+X combo worked. If not, minimizing-maximizing the RDP client
  window helped it complete the display updates in the background.
  
  In fact, I couldn't reproduce this problem with it now using the
  same Windows server by MSTSC, which gives problems when packaged
  into rdesktop/uttsc + X11 + SunRay protocol. To be honest, I have
  not yet tried the "bitmap updates" mode of rdesktop with this.

  So, I believe the problem is somewhere in the latter stack of
  protocols and software implementations.

  Has anybody had it? Are there ready solutions (server-config tweaks
  perhaps, or RDP client command line params) or submitted RFEs?
