[Dx4win] anyone help with rig files?

[george]

I'm trying to stop the frequency updating in the QSO window to stop the
problem I have with my Icom 7600/PW1/computer CI-V data clashing.

I would like to open up the rig file for the Icom 7600_500hz which is a .rig
extension but I cannot open it.I know in older DX4WIN versions I could open
up the various rig files but since they have been changed to .rig I can't
open them.

Any help?
