Clicking Cancel on a running Recipe causes hang (spinning cursor and says application is not responding and I have to force quit) 1 out of 3 times. This has been happening on several Macs for several years through 2 or 3 different OS upgrades. It happens with any Recipe that has been running for several hours. What do I need to supply to find this problem? Doesn't produce a crash log so may have to do a Sample Process with Activity Monitor when spinning. Don't know if it is the same problem but after client has been running for a day or so it makes the whole machine become very sluggish and have to be restarted. You can see the icons in Selection mode at bottom of screen being erased and then redrawn real slow. Maybe one icon will come back after 2 or 3 seconds and then the next one will be drawn and then 2 or 3 seconds for the next one etc.
