Huh, when I attempted the build here (LMDE2), nothing apparently happened. Go figure, I'll give it another *shot.
Sorry, no experience with tsnet (never had a use for it) or the browser widget here (I did mention I rarely use the later IDEs, right? )
* Tried all the standalone settings I could think of, even the ones I guess were left in it from when you built it, and couldn't get it to build for anything. The IDE was 8.1.4, will try switching up to a higher one in a vm.
*Edit - forgot, can't get past the sign up for an account thing on linux with 9.x
*Edit 2 - built it from Windows 10 with Lc 9 for 'nix, but no love, just displays a blank browser widget on 'nix
