Apparantly, I can't run multiple instances of Miranda Portable.
This is strange, because I googled it, and I found someone had posted a "bug" on miranda dev and it was marked as solved because according to the developers, there isn't any check so that should work.
So I'm guessing the problem is with the MIM portable launcher...?
Also, what does MIM actually do that's not portable, warranting the use of a launcher?
PS: By searching the forums here I found out that Mozilla portable launchers support a setting "allow multiple instances" by placing an ini in the root (which, btw, screws up the "official" directory structure if I read that draft correctly, after all, that says there should only be 1 html and 1 exe, placing the ini there screws the backup mechanism I think?). Maybe there's such a thing for the miranda launcher too?
