Under circumstances I do not know yet, my Jade (regardless which version: 2.10 .. 2.17) is NOT able to make a connection to a remote server and throws strange errors: (like SciLexer is not a valid Windows application or some Windows Hooks are not working).
Generally I work now under Wine - but when this error is happening I switch to a Windows running in a virtual box and the same error happens there too (same error messages) !!!!! This is *very* strange.
The only solution for me is to start the Dolphin IDE (under Wine) and start Jade from within Dolphin and that has always been working yet.
Sometimes I noticed, that in these situations even a new Gem has been created at the server - therefore Jade has made a connection to the server somehow.
