Notice that my forward and reverse arrows in the effects editor for moving frame by frame through the effect work has stopped working. It did work in v8.6.1 for me but has stopped working after going up to v8.6.3 and then back again. Had quite a bit of effects editor wierd behaviour since moving up and then back again. Corner pin, rotation points show then disappear leaving you blind to try and manipulate the points. Did a full clean uninstall of avid and system and problem continues to persist.
