Using: Xara Photo & Graphic Design 6
AMD Athlon II X2 255 Processor 3.10 GHz
2.00GB (1.75 GB usable) RAM
64-bit OS

I follow the tutorial in the Xara Help, but cannot get the results shown.
I draw the circle, compose the text, and set it to the middle
Select both circle and text
Arrange/Fit Text to Curve....the text appears around the lower, right side of the cirle
After all this I am unable to manipulate the text
(It's a piece of cake to do this in Publisher 2010, but it has some minor problems in appearance)
