I have this problem after upgrading to Maverick, too; xev shows a ButtonPress event (with not ButtonRelease) for any XF86 KeyPress, and the left click stops working after that.
I use a Microsoft Digital Media Keyboard 1.0A (045e:00b4) and a Microsoft IntelliMouse Optical (045e:0039).
I have installed the update provided by aubergine and will now restart to test it.
