v9.1 Beta: "Device dropdown list" works incorrectly if run MC with para /OPEN

[AriesTruong]

Hi Mathias,

I add MC as item in Context Menu so I hit this case. This case does not happen if there is no instance of MC.
MC v9.1 build 2548

Steps:
1. Run MC, minimize MC
2. Right click anywhere in Windows Explorer (not to right click on file or folder. Only click background) and call MC from context menu
3. MC open this folder as tab in MC well

As observation: "Device dropdown list" doesn't works with this tab although others tabs work well with "Device dropdown list".

Note:
This issue doesn't happen if we run cmd from MC to test this case.
