Hello LeBear,
I have created a sample project based on the description that you have provided, but did not experience different behavior when testing with Q2 2009 and Q3 2009. Here is a
link to a video captured while running the project. I believe the problem is caused by some custom CSS that you are applying to the Dock control. With Q3 2009 we have introduced an improved rendering of the RadDock control that solves number issues reported by our customers. Unfortunately custom CSS code that previously worked might not work with the latest version.
So can you please modify (or send a) the sample project (the source code is pasted below) so that we can observe the problem locally?
To set the width (or height) to the RadDock control use the
Width property.
Here is the full source code of the project:
Sincerely yours,
Pero
