corner rounding widgets
I am making a T with two rectangles and I combine the two to one shape
then I want make some corners round, but the round corner widgets do not appear!

in the rectangle you see the corner widgets
but NOT in the T

I press CTRL but the corner widgets DO NOT APPEAR and all the blue lines are gone
In new other drawing it worked?

this corner widget appear only when I press CTRL key
I am working in windows
In a new drawing it works, but in the drawing I am working not?
