Backend is started twice #24
Description
In case the backend process had stopped because of a timeout.
When "follow reference" is invoked by the user.
Then the backend process is started twice.
The output below shows that two lines "RText service, listening on port 900X" but only one line with the program name and version (which is output by the backend directly after the line "RText service, listening..."). This is a hint that the first process is either killed immediately or that its output doesn't go to the console window.
