Chris, I just ckecked and realized that the problem is only with CS5 64bit, I'm on windows 7. CS5 32bit works as you described.
However even if it worked this doesn't help me anyway. I constantly change the size of the brush because I mostly paint but still need to know which brush preset I selected last. Please make a feature that highlights the last brush preset used - may be in a different way (color) if it doesn't match the current brush. It is real pain to find the needed brush. I have hundreds of brushes showing on my 30 inch monitor and I need them all. I spend a lot of times looking for recently used brushes. You can also implement recently used sorting order. I hope this is not very difficult to implement. Im sure that a lot of artists use many brushes like me, just look at all Photoshop painting instructions videos, even the tutorials are boring when watching how long it takes to find and select the needed brush.
