As a follow up, my sister-in-law bought me some T-max 100 film for Christmas. I loaded the roll in the back that has been giving the problems described above. After giving the insert gearing a few squirts of Zippo lighter fluid, the counter advanced to 10 but stopped there. Progress in part but still disappointed. Oh well; I'll see how the second roll does and perhaps send it in for repair. Thanks to all for showing interest in this issue and offering some advice.
