Well ... first hand, your pic isn't working for me, so no chance to see the "this" of your complaint.
Second hand, I suggest using 2.64, where we have no problems exporting the animations. Be more precise on your problem, and I could tell you more.
I wish I could give more information but I know less than nothing about this, all I know is when I try export an animation model to ogre xml its doesnt give a .skeleton l.xml file and gives an error but it works with all other file types, the ogre xml does work with non animated models. Could this be a problem with the exporter ei corrupt or something?
