When I load DMD 2.1.4 and select a project that will load with the DM-Simulator, first I notice the time lag of the simulator loading. Next DMD just sit there. Click on Project Browser and both DMD and DMSim lock-up. Unable to exit the programs I started Task Manager. Then selected DMD or DMSIM then End Process. Both will stop running and unload. But then you are unable to exit Task Manager. Then you will have to Restart windows.
The reason is not all of DMD did not unload. I found this out when I took Task Manager to the next level and started the Resource Monitor. Under Memory, select DMDesigner, then right click then select End Process Tree. Then i was able to exit Task Manager.
Work around is to start DmSim first before starting DmDesigner.
My equipment list and configuration is included in Speccy.zip file.
