thank you for your quick reply and the work around. I have been testing the following use cases to see for which the the bug occures (always with closing afterwards):
- Opening a file (bug does not occure).
- Resizing a file (bug occures).
- Merging two files (bug occures).
- Hibernation disabled (bug does not occure for any of the above scenarios).
Besides the afore mentioned bug I became aware of a somehow related issue. After resizing a file, when the save dialogue appears, it is not possible to overwrite the file that was just resized. This is very annoying, since it forces you to first make a copy, delete the old file manually and then rename the copy. Would be nice if this could be adressed together with the bug, since they seem to be close to each other.
