I have seen some videos of people doing stuff in the CK, and when they click the *All category in the object window, it opens up almost immediately. When I try to do the same, it takes a really long time (10-20seconds) and the CK is frozen during this time. That's REALLY annoying, so I don't use the *All menu because of this

So I'm just wondering were those videos I saw just my imagination

or can you actually open the menu that fast?
In case it matters, I have a 3.2GHz IntelCore i7-2600 CPU, 8 GB of RAM and the CK is installed on my SSD drive.. So I'm thinking it's not a hardware issue!
