Yes, I've had intermittent results with the edit coordinate systems also.
When it works, it is great, but sometimes I just CAN NOT get it to respond.
The button goes down, it lets me select the origin, or the x axis, or the y
axis, then it prompts me to select, and I can't select anything. I haven't
had time to figure it out either. If the icon goes down, I would expect the
command to work.
I also tried rotating text first, and was dumbfounded to find that it wasn't
possible (is it?). Such a simple task - why should it be difficult?
