Cannot convert null to type "System.Drawing.Point"

I have a Show-ADTInstallationRestartPrompt that after being minimized pops up again after the timer expires to prompt again but it also comes up with this error.

************** Exception Text **************
System.Management.Automation.SetValueInvocationException: Exception setting "Location": "Cannot convert null to type "System.Drawing.Point"." ---> System.Management.Automation.PSInvalidCastException: Cannot convert null to type "System.Drawing.Point".

This is the line in my script:
Show-ADTInstallationRestartPrompt -NoCountdown

Is it possible to either get rid of this error or have the restart reminder not pop up again?

Same as with the other post; please move onwards to 4.1.0 as all the classic UI code has been rewritten for the new client/server model while maintaining the same look and feel, but more robustly implemented and with better HiDPI support.
