Hi Albert Shenker,
Thank you for your detailed feedback. We will consider the issues that you describe as we develop our skins in the future.
The problem with the RadMenu Office2007 skin had to be solved this way because of the integration between RadMenu and other RadControls (e.g. RadTreeView, RadGrid). We will do our best so that every skin that is made obsolete is made available as external so that one could easily revert to the old version of the skin without much hassle.
Sincerely yours,
Alex
the Telerik team
