I have just upgraded to the new release, I was on 2008 Q3 before. I have a control that uses a radToolBar and the skins just don't seem to fit properly anymore whereas I wasn't having any difficulty at all before.
The Control:
It is being placed in a div on a page:
And this is what it is showing:

I also have some raddocks and the skins for them don't seem to be displaying properly either. They look weird in IE7 and are just flat colurs in firefox. I am pretty certain that both problems are caused by the same issue but I can't find anything at the moment. They were all working perfectly well on the last version I had which was 2008.3.1125.35 the version I am on now is 2009.2.826.35
