I'm not sure what has happened. I have my mouse wheel set to the object snap menu (mbuttonpan = 0). Until this morning I was able to execute a command, click the wheel button to bring up the osnap shortcut menu, and key-in the osnap I want, i.e. E for end, C for center, etc. Today when I try this, the shortcut menu pops up, but when I key-in the osnap, nothing happens. It's like it is ignoring my keyboard entry. I've checked my settings, but don't see anything wrong.
Any ideas would be appreciated.
