Bringing a thread back from the grave here.
Searching the forums for something like this brought me here. I got the same issue that exporting takes quite some time and in most of the cases I just made changes in the event sheets.
I've turned off png recompression and minify script when I do an export for testing purposes but it still takes a couple of minutes.
So in the end I would still be pleased with a 'just export c2runtime' functionality.
p.s. reason I'm exporting for testing purposes is because I use AJAX which needs te be executed from my testserver.
