Re: Please separate the May 2018 and May 2019 win10 versions
Just updating it seems to have been fixed by keeping just 1 merged 2018 version (while newer versions were added later on).

Re: Unicode support for UI
Just updating it was eventually fixed by integrating SC in the main UltraVNC in the v1.4 branch (first seen in 1.3.9-dev1).

Thanks for the new release! But I thought the whole point of integrating SC in main UltraVNC was to avoid messages like these, wasn't it?No UltraVNC SC version at this time.

Re: UltraVNC 1.4.3.6 - Feedbacks
In that case what worries me is what if there's a sudden crush and then the very people that need UAC the most would be left without it...
Does the program at least have something like "on exit perform" that might still run in some crashes?
Not that it crashes a lot, but sometimes you might restart ...

Re: UltraVNC 1.4.3.6 - Feedbacks
I was just asking in general - did [DIS_UAC] always turn off UAC during the session (and restored it upon exit) or is it a new feature?
I'm not talking about the specific fix that affected restoring, but about the general feature.

But the default https://www.uvnc.eu/download/1400/helpdesk.zip already includes [DIS_UAC], meaning unless you manually removed it then you did use it.

BTW, I still hope you can answer - why do repeater connections warn "Accept without authentication", but Direct Connections don't warn?
