No luck yet. I went through my music CD collection, because they were in there for a while, but it's all music now. All the tech CDs are somewhere else, and I don't know where right now, since I almost never use them any more. But I'm sure I didn't throw them out, and I live alone, so they must be here somewhere. I'll keep digging, and look at my old FTP server at work tomorrow - I think I recorded them all on there. Might be a safer bet than a 20-rear-old CD-ROM, if I can get it started. It's an ancient Linux server, running SUSE, and it always takes a bit fiddling to get it running, since I do it so rarely.
And I found out why my menus were disappearing - there is a Temporary flag in the Add method, which I had set. Rereading the Developer's Handbook turned that up. I had just copied that line and not paid attention to what I actually had coded in it. Changed that flag to false and my RC menus stay put.
