Not sure if this is new to RC1 or has been there in DF20 all the time. I'm using the dark theme, and all its defaults (I've not amended anything). I open View and then Arrange Objects. I tick one of the boxes to activate one of the entry objects, but I cannot see what I'm typing because it seems it's using white text on a white background. Obviously, if I then de-select the box, the DEO becomes inactive and I can see the value. But, not ideal, obviously.
