Hello John Clogg, @ 3000-l,

RE: QTP and VT-MGR

------------------------------------------------------------------------
We had a rather interesting problem.  A programmer reported that a
particular QTP process would sometimes run very slowly.  When I watched it
with GLANCE or SOS, it was using about 1% CPU on a lightly-loaded machine,
and spending about 98% of its time waiting for "Terminal Write".  This is
not a process that does terminal I/O while processing the data -- it only
reports its results when it finishes.  She could interrupt the process with
a control-Y, at which time it would prompt with "Do you wish to proceed?",
and Glance would show a wait for terminal read.  When she replied "Yes", it
would go back to waiting for terminal write.  The wait was not permanent -
the process was progressing through the data, albeit very slowly.  I had her
disconnect and reconnect using Telnet instead of VT-MGR, and the problem has
not recurred so far.  We are using Reflection version 7.0 on Windows 2000.
Can anyone offer an explanation?

a good keyword to search is "xcontrap".

here is one of the documents:

This problem is typically a programming design problem which is visible
over the NS-VT Client due to the 'smart' VT client.
