Hi Bob,

Last night during a run a 60 second exposure did not complete for over 3 hours. The odd thing is that everything ran just fine after that. I'm assuming this is an issue with Maxim or Diffraction's driver but thought to post here just in case this has been seen before. Here's a snippet from the log.
