[Dx4win] Access Violation using RTTY to KAM

[John F. Samuels]

All of a sudden I am getting the following message when I enable my KAM on
COM1:

An Exception Occurred:
Access violation at address 0057A148 in module 'DX4WIN.EXE'.  Read of
address FF FF FF FF.

If I enable the packet window (same port, same device) it works fine - no
errors.  I can force RTTY here and it works fine too.

I've done all the obvious things, rebooted, ensured no IRQ conflicts, etc.

I am running version 5.03.
