Hi Peter,
I wish I'd posted 3 hours earlier. Your analysis pointed me in the direction to fix the problem. Thanks so much.
First, you're right - I was very confused - but you straightened me out. Yes, I'm using GPSOut for the moving map, not WideFS; however, I've been launching WideFS for years whenever I used the moving map because I thought I had to. Dumb!
Second, I found that WideClient wasn't receiving any info from the FS9 machine; it was indeed disconnected. But I suppose it was connecting a few weeks ago when I had this working. So something messed up the connection. In any event, I read the manual and added the line you suggested to the WideClient.ini referencing the IP address of the FS9 machine. Once I did that, all was working fine.
Finally, I have valid registrations for both FSUIPC and WideFS. The email address used by my simFlight Network forum registration is a real old one and is not the one I used when I registered the programs. I'll email you the registration info shortly just to confirm this, and I'll try and change my email address with the forums so all is up to date.
Thanks again for all the help, and especially for explaining to me just what was going on here.
Robert
