keyboard shortcuts - AutoHotKey and VirtuaWin window switching

I've got a AHK script that looks for an active Emacs window and switches to it. However, since I'm using VirtuaWin now, this script stopped working -- it only works on the virtual display where Emacs actually is, but not on others. Any suggestions on what I can do?

Answer

DetectHiddenWindows, on

would detect it, but switching to the workspace it's on could be complicated.
