ERROR: Unable to set the delay before watchdog terminates to 15 seconds

This is a fairly common issue that pops up for me when using Ansoft HFSS (v14) or Q3D (v10) in Linux environment. I figured I'll post a thread showing how I fixed it in case it helps someone else.

If the error shows up, clear the main window by typing:
> mv ~/.mv ~/.mv_old

I found this useful. Other techniques are available here.
