Ok. I'll tag this topic as "not a bug" then.
But if you find anything new that might help to understand the cause of the problem, feel free to post here and we'll work on it again.
This bug will be fixed in the next release.
Thanks for reporting it.
I have a similar setup (HTPC under Win 7) except for my files which I stored locally instead of being on another computer.

I suspect the problem might come from the mapped drive although I don't know exactly why. I suppose the drive letter stays the same (otherwise a complete rescan is a normal behavior as files are identified by their path).

If you're interested, I can build a specific debug version for your problem (which would log exactly what happens during the scan so that we can understand why Ubooquity thinks the files have disappeared).

This screen is shown by default when you don't have configured anything yet. So it's perfectly normal in your situation.

As for the "page not found", I'm puzzled.
Could you send me your log file ? ("ubooquity.log" from the "logs" folder in your working directory)

Like Paul Marvel said, some browsers have a user triggered fullscreen mode that will work with Ubooquity as with any other website.

But I suppose you are thinking of this kind of fullscreen. Harder to achieve. I'll consider it when I work on revamping the online comic reader.
When you click "Set password", Ubooquity should take you to the exact same URL than the one already displayed on your browser address bar (for instance: http://10.0.0.1:2202/admin) and a "webadmin.cred" file should be created in the working directory of Ubooquity.

Could you check if the file is created ? And check if you see anything suspicious (warning or error) in your log file ?
It should obviously not happen. For the moment I have no idea of what might be happening.

Could give me a few details on your setup ?
What kind of device (PC, NAS...) ?
Which OS (Windows, Linux, OS X...) ?
And if you are using Linux, are you using symbolic links for your comics collection ?

If you have a partial log file of the moment the removal starts, it would also help.
And just to be sure, we are talking about the "Launch new scan" link in the "general" section, right ?
