Hello!
I think found a bug in live preview. I have a HTML file on this path:
C:\Users\marko.milutinovic\ownCloud - skupno@oblak.mycompany.si\1603 - Informatics\Razvoj\Promet\MarinaLab\Dev\Client.Web\Frames\Check.pas
When I strat LivePreview nothing happens. I found that Live Preview server has started in the taskbar. I open the user interface ant there is the path until the first space.
The browser is not selected (but I set it in settings) and it’s not started. When I set the browser and click Show Preview, I get this:
Hope it helps 
Kind regards,
