I've this problem with animate cc on PC, win 7(it's happen also in older flash versions)
Basically if i select a graphic, and flip it Horizontal (pic 1), the "Transform Panel" show me "180" in the "skew" property (pic 2).
But if i deselect it (pic 3), and select it again (pic 4), the "skew" property doesn't show me any value. But I know the value should be "180"
In order to "see" the right value i need to manually select the skew box, and it appear the right value (PIC 5).
If I try to select the object 10 times, only 2 times he gave me the value, all the other attempts gave me a 0.0 or nothing
This is very boring, because I work often on files that not created by me, so I can't go on every single element and manually check IF is flipped or not.
I work on different pc, and it's happen also in older versions, so I know is not an istallation problem.
Does anyone can help me to understand why this happend? and or solution for that?
Thanks for the detailed report. Will investigate and update you once we have a fix. Looks like this doesn't happen if you select an object if some other object/shape is already selected i.e., doesnt happen when you switch selection from one object to another. You may want to use this workaround until it is fixed.
