X6 TechSuite - CorelDraw Embedded Connect frozen

Found an interesting issue while evaluating X6 Tech suite:-

Using CorelDraw X6 I use the embedded version of the Connect docker.  After the first couple of times working correctly the left-side tabs / expander buttons are now non-responsive - cannot open folders, etc., on the left-hand side Explorer panel.

I can still use the stand-alone version of Connect correctly but the embedded one doesn't work.

Notes:  I did have to run Repair on the installer a few days earlier to solve a different problem and this may have had an effect on Connect while fixing  the other issue (the "Edit Bitmap is faded out" issue).

 

Running on Windows 7 Pro 64-bit

 

Not sure if there are any other potential system conflicts which might be causing this.

Have not yet tried to run repair again in case there are other solutions to explore first.  I want to try discovering the source of the issue not a brute-force solution like Repair.
