Downloaded 5 this morning and it is wonderful.

I'm not sure if this a bug, or not.

In Lights Out
In the new docking mode
Trying out the Sample Tracing Image
Had Tint Tone Picker docked
Had the numeric sliders selected in the colour wheel
... then when I went to Select Colours from Original the two parts of the colour wheel were superimposed ...

... it may not be a bug but a snazzy new feature ... anyway ...

BTW, where should we report these little things? Here? Somewhere else ... ?
