V4.2 KNOWN BUGS AND ANY KNOWN WORK-AROUNDS
1. Single line fields:
Changing the font and text attributes do not work!
This is fixed in HN v4.21 coming shortly.
2. Animation and sprites:
The RB sprite engine occasionally does not respect a sprite's transparency!
Resulting in white background around the sprite.
There seems to be no workaround as the RB sprite engine was deprecated.
Only solution a new sprite engine.
