Allright... it was gone for a couple of days, I changed the Attach Mode to Default, cause it was set to Alternate, and now I tought how about changing it back to Alternate and see if it comes back, and it did...
But somehow changing back to Default or closing msmsgs.exe doesn't work...
Everytime I start msnmsgr it automaticly starts up msmsgs and even if I close it afterwards the option is still grayed out.
Maybe after a reboot it will be ok, I don't want to restart my computer just now, but tomorrow when I start my computer again I will post again to tell if it's fixed or not.

Reboot didn't help
