IBM Client Access Express R4V5M0 typing delays

[Smart71]

Hi,

we are using client access express V4.R5.M0 SP66153 on a
Windows 2000 Terminalserver (Novell Client 4.80, Groupwise Client
5.5.3, Office 97, Acrobat Reader, IE 5.5).

Whenever an application takes 100% CPU time, there is no input in the
PC5250 emulation possible. After the CPU gets free time the emulation
screen updates with the last keyboard input. Telnet from Windows 2000
has got the same problem.

With Mocha 32 or Nexus PC5250 emulation software there is no problem,
if the cpu comes up to 100% for a few seconds.

How can we solve the problem with client access express ?

Thanks,
Thorsten Witt
