I have not tried the latest release (version 8.0.284, I beleive), but I have had the following problem on the last few builds.
I open "Record Sound", set it up, and then record a track or two from a cassette. When I exist "Record Sound", it does not save the track(s) I just recorded. This is the main focus of my recent use of MJ over the last few months - recording my cassettes so they can be burned to CD. I have done a bit of this, so I don't think it anything that I have done (although anythings possible). Any help with this would be GREATLY appreciated. I did do a recent uninstall/reinstall; when I installed version 8.0.275. I guess I could have lost some setting or other, but, if so, I do not know what the settings might be.
