Just to flag an “unhandled error” that occurred to me but did not crash Tropy in the end, but I thought would be worth reporting.
I was working on Tropy and then suddenly as the attached error message happened and the image no longer displayed. I clicked on other images in the same item and they did display; I returned to the “problem image” and it still wouldn’t display. I clicked on other items’ images and they did display as well. I returned again on the “problem image” and it displayed as if nothing had happened before…!
[I’m not sure the problem I report here is similar to that mentioned there: Appearance of 'unhandled errors']
