Recently, I changed my default setting in Maxim to Save Date in Unsigned Format. I did this as the PI forums suggested that saving the data in signed format sets the range of ADU from 32768 to 65,000. This in turn causes dramas for flat fields.

Looking at my images, the unsigned setting results in this odd appearance while the signed data looks fine.
