Hi,

We're making extensive use of inherited user controls in our application and
since we converted to RC1 we commonly get the following error when trying to
display the user controls in the designer. We've tried all the usual things
like rebuilding, exiting visual studio, opening ancestor controls in the
designer before opening descendant controls, etc. Sometimes the controls will
load in the designer and sometimes they just won't and I can't seem to put a
pattern to it. I've tried searching for this problem and haven't found
anything that specifically addresses this issue. Is this a known problem? Any
suggestions?
