That helped, thanks.

New popup palette seems to react on right mouse click in a different way than it did before.

1. in some cases (still cant figure out which exactly) the palette appears and disappears the same moment. It seems it thinks that if i released right mouse button then i do not need the palette anymore. But i do :)
2. in some other cases (also cant figure out when exactly) the color is selected before i can see what color i am selected. Looks like it is already selecting some color while i'm pressing right mouse button. For some reason, in many cases it selects very saturated and bright colors (may depend on selected Advanced color selector model).
