I'm finding that in OS X there's a delay between right clicking and actually seeing the context menu (or whatever I'm trying to get at).
I've never noticed a delay like this in other operating systems. I wonder if it's a 'feature' (or otherwise) of OS X.
It's not a long delay, it's probably ~250ms; enough to cause a little frustration anyway. The machine obviously isn't stressing about it, it seems to just be an arbitrary delay.
