Is there a known problem with 64bit Windows

Hello,

we have the following problem with Windows Server 2003 (x64 Edition) and
Windows Server 2008 (64bit).

It happens sometimes that a connection with the transport (TCP/IP)
hangs. If we set transport.active:=true then it throws no exception but
this function seems to hang. We are waiting 10 minutes and it is still
on this source line. The problem is, that it throws no exception, so we
don't know what the problem is.
Other clients, which are already connected, can work without problems.

If this happens, we have to kill the nxServer Process und restart.

We have this problem only with 64bit Windows.

Best wishes
Bernhard
