MediaMonkey 4 currently in beta already has a fix for this issue.

will fix, or has fixed (i.e. should I go get the beta)

This is a known issue caused by Internet Explorer 9. MediaMonkey 4 will fix this issue.

In Win 7 64 bit, MM works fine, but if I simply grab a window and move it or resize it, it becomes non-responsive. The music keeps playing to the end of the song, but that then stops as well. The top of the window shows (Not responding)

I can move the window again, but the Not responding stays until I force close the application. I can then start it again and everything works again, until I once again move or resize the window.

Anyone else find this happening? I'm still using Mediamonkey because it works, I just am careful on moving anything.
