My original thread on this topic now seem to be locked, so I'm trying again.

@astro - Thanks for your suggestion. As luck would have it all my platforms seem currently to be running 6u29, which does sound like it's part of the problem.

@API Support - @RequiresFullAccess makes the problem go away for some strategies, but not all of them. The "alternative console implementation" seems to cure the "hanging" for all strategies on all platforms, but on UNIX the console output appears now to go to /dev/null. If Dukascopy have been aware of this problem since November, why isn't it fixed yet? Doesn't exactly inspire confidence, does it?

Cheers,

Jim
