"What's the process?"
In a windows envirovment a process is either an application (exe file) run by a user or service (exe file too) but that is running in a background.
So, what I am saying is this:
quartus_sh.exe is running when you finish compiling a project, and that is not an issue. The issue is with a multiple quartus_sh.exe running at the same time (depending how many times the project is compiled).
However, I can live with it. But, it is just enoying phenomena.
It would be much better when a new instance is created (quartus_sh.exe) the old one should be killed.
Thank you
