Windows 11, Indesign 20.2
Problem summary: when saving a file to a network to which the connection is lost during that save action, ID completely hangs and might also block the entire system.
Steps to reproduce:
1. Open any bigger INDD from a network drive, so the saving action takes some seconds.
2. Change something and click save, then simulate a broken network connection by pulling the LAN cable
Reaction: there might or might not be that "Save document" overlay with progress bar being at 0%. At this point, ID has two problems:
a) There is no timeout. It would try to save the document, like, forever.
b) The "Cancel" button, should that overlay be shown, has no effect at all.
