That's really strange as this isn't a known issue in MediaMonkey 4, but a known issue for certain MediaMonkey 3 releases. You should try installing 4.0.3 which is the latest release and if that fails send a debug log (step 4b) to support: http://www.mediamonkey.com/forum/viewtopic.php?f=7&t=69

Thanks Lowlander for responding..

I have ie 9 loaded on new system. I never use it.. I use Firefox 10.0.2.
I opened Autotag window last night and MM froze as soon as I opened it??
Sometimes I can open and as long as I don't re-size its okay. I really liked
the autotag feature being fixed in 4.0.. I had been waiting on loading 4.0
until I got my new computer. I guess I probably will have to try 3.25 if I
can't get 4 to work

What version of Internet Explorer is installed? I've not seen this reported on MediaMonkey 4, but this was an issue in some versions of MediaMonkey 3.

When I click help>about> says 4.0.2.1462

This is an old bug from MM3, are you sure that you are using v4?

I just installed 4.0.2.1462 on my new pc.
Win7 64 Home premium, amdfx 4100 8 gig.
When I try to resize the Autotag from web window MM will freeze(Not Responding)
on the autotag window. If I click on main MM window it also goes (Not Responding).
If I try and enlarge vertical or horizontal Autotag window MM will hang every time.
I can use the open Autotag window as long as I don't try to move or resize.
The only way out from hang is to end MM from task manager.
Has anyone else seen this???
I sent trouble ticket to MM support so I could attach MM application .DMP file and screen shot.
