Ouch, sorry, didn't encounter those issues, will push a fix soon.

Select Motors & Configuration and Motors tab... upper stage still selected... left-click configuration to select motor... turn off any stage to error.

This is intentional, the motor mount is only selected when the motor table has gained focus. That ensures that the component selection does not always change when you switch to the 'Motors & Configuration' tab. So only an active click in the table triggers the component select, as it should be.

Does the final commit fix the issues @hcraigmiller?
