I am also working on an Intel Mac and every time I open proanimator from inside after effects the controls do not show up. By that I mean that I can see the preview window but absolutely no controls, everything is just blank white.
The only way I’ve found to work around it is to use the expose feature of OSX 10 (squeeze the sides of the mouse to reveal all open windows) and click on another application like an open text document and then click back on the proanimator window.
This obviously is some sort of bug that will hopefully be addressed soon as it is seriously impeding my workflow.
