I have a strange problem. Please help.

I want to use Messenger Plus! Live, MessengerDiscovery and StuffPlug with my Messenger, however as my computer is shared with my other family members and they don't want any add-on other than Plus!, I have created a copy of the Messenger folder in .../Windows Live/ directory. Then I pasted loaders of those three add-ons in this directory. In the original Messenger folder, there is only Plus!'s loader, msimg32. I start Messenger from my personal folder, other people start it from its original location.

But when I start Messenger; MessengerDiscovery and StuffPlug doesn't load to my Messenger because the original msnmsgr.exe starts from its own location, so only Plus! is loaded. When I delete msimg32 from my personal directory, Discovery and Stuff work fine but this time there is no Plus!. I tried deleting other add-ons' loaders one by one and I am now sure that the only problem is Plus! here. I mean even if I didn't install Discovery or Stuff, the Messenger still wouldn't be started from a personal folder with msimg32 in it. So I think Plus! causes the Messenger to be started from its original location. I tried from my brother's Windows account, there is no problem with his account. Messenger is started where it is initialized so Discovery and Stuff are loaded successfully along with Plus! as well.

Why does it do this? How does Plus! cause such a problem?
