Suddenly Alt+W isn't toggling viewports

[John.McWaters]

Suddenly, Alt+W isn't toggling viewports anymore in 3dsMax for me even though the hotkey is set to it in the menu. I noticed it started happening shortly after I installed the Rebus Farm plugin. Has anyone had any issues like this with a solution?

Nevermind, I think I figured it out. Apparently, I had deleted all but one viewport so there were no more to toggle to. I think Rebus may have done that, but I just had to reset it to the default 4 viewport view.
