Enrico,

I have still rather confused as to exactly what is supposed to be
happening.

Can we leave the grid issue out of it for the moment - that can get
really confusing. Lets concentrate on the problems with the UpdateBar
or NavigationBar - as these are much simpler components.

From the fact that you could give me a line on which the error occurs,
seems to indicate that the problems are happening when you execute the
program, not at designtime. Is this correct?

What is the callstack when the problem occurs with one of the Bars?
