The Python Console is not compatible anymore with Visual Components 4.9 and future releases.
I will discontinue it for now because a crucial interface is not part of the .NET API anymore.
The Python Console got a workaround and works again with VC 4.9+.
The only downside is, the text window remains white disregarding the chosen Python editor theme.
The new version 2.1 is available in Addon Store from VC 4.9 on.
