Buzzsaw causes nonbreakable loop

[Anonymous]

Has anyone else had this problem.

In the open file dialog box select your drive and then by mistake forget to
click in the main window and scroll thru the drives instead of thru the
folders in the drive you initially selected. Since Buzzsaw is at the end of
the list of drives it gets selected as a network drive. I now get a
buzzsaw.com ProjectPoint dialog box asking me to install projectpoint. I
don't want to install projectpoint so I click Cancel. Internet explorer
still launches and upon returning to AutoCAD I get the exact same stupid
dialog box. Click ok the same thing happens. Its a nonbreakable loop. The
only solution is to endtask AutoCAD. Not a good solution if you prefer to
save your work before you exit.

Does anyone know how I can remove this "improvement" from my systems?
