Rick says it is not work for tilting. Here is the exception:

Exception in thread data binder handler thread:

and also several of these, although not sure how that would be related since they seem to be more GUI related:

Anchi, can you review r14913. I think it should fix the exception that Rick reported, but I still don't know exactly how that relates to AutoExposure not working. I'm just going to have him try it and see if the problem goes away.

I think Rick's exception message comes from Editing the raster points in "Final Raster Targeting". It need to handle meter targets properly there.

In my testing it complains that the meter targets will not be processed because it is added to the list.

r14996 adds the options to limit the exposure time and number of attempts to change exposure time.
If either of the limits is exceded, it will give up and reset the exposure time to where it started.
