My Canon 1100D (AC powered) only saves every other image. (And it's exactly every other image - no randomness that I have seen) I have changed the USB cable and tried different USB ports and USB hubs without success. I have also tried increasing the delay between images. No change. Has anyone else seen this problem?

Attached is a log file showing 6 exposures. 3 actually got saved. I can upload my settings if needed.

Thank you,
Ollie
