There are a couple of issues that need to be mentioned about DMD2.
1. Not so critical issue: When in edit mode the Instruction toolbox tool tips can only be turned off by right clicking inside the instruction toolbox and uncheck option Show "Help" Tooltip. Don't go by what is shown in the tooltip at the bottom to turn it off.
2. Critical issue: If you are H2-DM1 cpu which has no ethernet port for modbus server and select one of the modbus functions by click and drag or double clicking on it, you will LOCK-UP DMD2 with no recovery of any edits not saved because the only way out is to terminate DMD from the Task Manager.
