I am clocking from the SX key; both serial and USB (I had to replace the serial key last week after I inadvertantly got it connected to 9V :freaked:  ). Anyway, it works fine at 9V so I don't think I have a clock issue, and yes, I am running it without the SX key.
 

I don't have the voltage reg. connected to Vss. I thought the drawing showed this, but it goes to 12V and to ground, with the output going to Vdd after the 10 uF caps. How should the regulator connect to Vss if other than this?

 

ps - thanks for the tip on the mclr. I thought as much, but wanted to make sure.
