Thanks yogi,
All of the issues you have posted appear to relate to either the uTorrent web server itself, or the browser.
Have you tried other browsers?
Perhaps try reading on the uTorrent forums.
I myself haven't used uTorrent much, and the binaries that I finally found were compiled sometime in 2012. Development on uTorrent for Linux doesn't seem to have been continued.
Since these actually relate to the web server itself, I think it should be possible to try and fix this. The web server itself is all contained in a single zip file that is accessed by utserver.
Perhaps there are other "patched" web servers for utserver that are available... I'll try and look around. If you find anything please let me know.
Cheers,
Clinton.
