In the same vein as https://forums.autodesk.com/t5/fusion-support/bug-parameters-dialog-opened-in-the-background-blocks-... I have found another case of Fusion blocking itself with its own hidden modal window.
I was replying to a post here and need to share a link to a document. So I copied the share link and continued posting, forgetting Fusion in the background with the share dialog open.
Meanwhile the WiFi dropped and I had to fix the connection. After that, going back to Fusion I found it showing a "network unavailable" message. I dismissed it and while waiting for Fusion to recover from the "offline" state I was clicking the window only to get back "window does not have input focus" chime. Only when after several clicks I clicked on the taskbar icon did the hidden share link dialog window showed up in foreground, I had totally forgotten about it, and I was able to solve the problem by closing it.
So at least this one should be easy to test: open share dialog, disconnect the network, see what happens...
