That too is also English (v. 6.2.0133)
I managed to find other posts referring to the same problem
here.
Turns out, there are compatibility issues with this function on the version of Windows in which you have.
I just tried this out with 2 computers, one running with WindowsXP, the other with Windows98 (the one I'm having problems with). With the function enabled, it'll only work for the user on an XP operating system rather than 98.
Hopefully, this issue will be addressed in an upcomming version of Messenger Plus!
Thanks for your help anyways CookieRevised.
