In our testing we do not see this problem. Skin changing is actually quicker than before. If skin changing is slow you almost certainly have an application which is either not responding or is being slow to respond.
Ive been using the same apps config since before Jesus was born, nothing, absolutely nothing is running on my rig that wasn't running before, or isn't supposed to be. All I did was update WB, from what I had to the private server one, then thinking that was the issue, I installed this version.
I installed nothing in between , the only change was the WB update Neil.
Should I do a full uninstall and try the public version from scratch?
