On an iMac 27" 2011 version running OS 10.12.4, When I have Vectorworks open, and I place the computer in sleep mode, upon waking, all programs on the computer run at 1/10th speed. Everything hangs up, thinks, waits. It only happens when Vectorworks is running. When it comes out of sleep normally with all other programs running I have no problems. Running disk utility and restarting seems to solve the problem, but what a hassle. This has been the case in the past 2 Vectorworks versions as well. Is there a fix.?
