Pinch-to-zoom stops working in Safari

i periodically notice pinch-to-zoom, using magic trackpad, stops working after i've been browsing in safari while.

i've been (pleasantly) surprised @ how useful find ptz, , use quite lot optimize size of text in browsing window. find quitting , restarting safari restores functionality.

i'm curious if a) other people have encountered phenomenon; b) if i'm doing wrong cause happen; , c) if there way - short of quitting , restarting safari - can restore during browsing session.

insight.

 

i have same issue, on mba. else works, pinching zoom stops. if quit , restart safari works again. queer.
