Haven't come across any info on this, but I apologize in advance if this is a know issue somewhere.
I've been using 3.4 and just updated to 3.5, and I'm having issues with the Inspector window not appearing to update. I will click a field to change a value, and the window will "freeze up" appearing that nothing has been changed, or turn solid gray. They only way to see that a change has been made, or be able to edit another field, is to undock the window and manually resize it, forcing an update. I have also been able to have it update by clicking a few other objects, and then going back to the original object.
Has anyone else seen this sort of behavior before, and can offer a solution? To clarify, this isn't an issue like the values being changed and reverting once play has stopped, it's simply locking up/blanking out the inspector window.
