I'm running Snow Leopard 10.6.8 on a 2008 MBP.
The right-click on my mousepad activates the context menu. A single right-click displays the menu, and it stays visible until I make a selection or click away from the menu.
For the last several months the right-click is no longer consistently "sticky." I.e., the context menu will disappear unless I click and hold. This is a hassle because it means a more complicated multi-touch manipulation of the mousepad.
I've scoured this forum as well as Google without finding an answer. All help is greatly appreciated.
