wine users - Aug 2008 - changed windows ver to 3.1: now winecfg & regedit hang

Greetings.

My problem is that using winecfg, I changed the Windows version to 3.1, and now
nothing wine-related will load. The first thing I tried produced an error
message that I neglected to save anywhere, and I have not been able to reproduce
it. Since then, every time I try to run anything wine from a launcher, nothing
seems to happen (though ps -e shows the process running), and when I try it from
the command line, it just hangs. This includes winecfg and regedit. So I
don't know what to do. Can anybody help?

Thanks.

Nevermind: solved.

I'm guessing my attempts to use regedit worked better than I thought they
did: upon rebooting, winecfg ran fine and was set to winxp, just as I had told
regedit to do.   weird.
