I am experiencing sort of the same problem but with all files with the .MP3 extension. (unable to delate, copy cut, rename etc. - unless I change the extension to something other than .MP3) If I attempt any of these, I get the error message " Windows explorer has encountered a problem and needs to close". Then as I choose to report the problem or not, my explorer windows will collapse and my folder settings will also change.

Do you think that the problem that you discuss about avi files may be the same sort of problem that I am having with MP3 files?

I downloaded and installed the trial version of "Universal Explorer" thinking it may work where Windows explorer would not. As I attempt to manipulate a MP3 file I get an error window that makes reference to "Kernel32.dll". Could this be a problem as like the one I read about the shmedia.dll file?

Strangely enough, I can still burn cd's using Roxio and I am able to drag and drop the files. I just can't cut, copy, rename etc.

Thanks in advance for any and all assistance.....fsumcdad
