Bumping this, because the issue is still there. And it got increasingly frustrating to me, because I'm trying my hand at some plugin development lately. Which means I'm opening and closing Construct 2 even more often.
And it happens a lot. On the average I would say every four times I open C2, the process remains after closing it again, and as a result I cannot preview anymore. As I mentioned Construct2.exe can't be killed from the task manager.
I don't do anything special, it just eventually happens. So I don't know what to tell in order to reproduce it. Maybe other users with the same issue can shed a little more light on this too (are there any?).
Running as permanent background processes are Threatfire, Avira Antivir and ZoneAlarm. I was fishing a little, trying to close the programs, but it doesn't seem to matter. C2 still behaves the same.
So yeah, I'm a little lost here.
