Hi Alston,

I'm experiencing similar issues to what you have described earlier.
Are you able to remember any details of what caused the problem and the solution or what I've missed and post them here?

Bernie.

It will most likely be some time next week before I get a chance to get on IRC.  We're hosting an ASME conference here in Tuscaloosa this weekend and I'll be busy with that.
 
That said, I'll be presenting what work I have completed with my plane and the amazingness of Paparazzi.

If you have time, I can troubleshoot this with you on the IRC.
