Switch between mobile/desktop doesn't work

(sorry for double posting, I don’t know if this should go to wptouch or wp-super-cache)

Hi,
I’m using V 3.7.7 of WPtouch, and 1.4.4 of wp-super-cache, and the switch between mobile to desktop doesn’t work.
For example:
http://www.r-bloggers.com/should-i-use-premium-diesel-result-no/
I also notice that when using ?something, the page will only be in desktop mode, for example
http://www.r-bloggers.com/should-i-use-premium-diesel-result-no/?something

Is that solvable?

Thanks,
Tal
