The release of v440 of the player brings a new possibility... The timer no longer needs to be continually reset to keep track of it. This means, for example, it's possible to detect stop clicked WITHOUT continually resetting the timer. :) Take note of the important restrictions listed in the project... BUT ALL BUGS mentioned below NOW FIXED with v442! :) See https://github.com/LLK/scratch-flash/issues/468 for the original bug report, and https://github.com/LLK/scratch-flash/pull/901 for the 'semi-fix' that the ST put in place (but which is still kinda flawed, leading to the issues noted in the project - see https://scratch.mit.edu/projects/75380478/ for a demo of the problem with local vars.) See https://github.com/LLK/scratch-flash/pull/913 for a fuller fix.
