Single desktop expose not working as advertised

bug

#1

the doc says:

https://totalspaces.binaryage.com/single-desktop-expose#mark-clicking-on-a-window-will-bring-it-forward-and-exit

for me, selecting a window in the single desktop expose does not bring the window nor even the app forward;
I mean, not always, it sometimes happen to work but it feels like incidental, some other times I end up in any of the other apps present in that desktop

that really ruins the feature for me
