Border radius quirks (issue reported)

If anybody else has been experiencing quirks with the border radius randomly changing when you select a shape, or look at it funny, I've logged a case: 01119513

My experience seems to be that a file that was created before the border radius config options is calculating the wrong radius on the corners, but visually shows the correct radius, but then certain interactions with the elements (not always) causes the shape to update with the, incorrectly, calculated radius.

For example, several buttons I had, had a border radius of 20px (~7%). Storyline showed this visually, but in the properties showed 47px (~17%). Selecting, editing, grouping would occasionally cause the shape to adopt the, incorrect, border radius defined in the properties.
