This right mouse option of trying to alter a database table faults when the
the user select the table performs a right mouse click on Alter Table. The
fault happens just as the Wizard appears.

Dear members of the board,

We would like to ask you to help us investigating the problems reported by Hank in last two weeks or so. Usually error appears at trying to open some of the database dialogues and error message looks like following:

[i]
Exception: System.NullReferenceException

Message : Object reference not set to an instance of an object.

Stack Trace:

DevExpress.XtraBars.ViewInfo.BarControlViewInfo.CalcLinkSize(BarItemLink
link, Graphics g, Object sourceObject)

at
DevExpress.XtraBars.ViewInfo.BarControlViewInfo.PreCalcMultiLineSize(Graphic
s g, Object sourceObject, Int32 AMaxBarWidth, Int32& ARestWidth)

[/i]

Based on the error description can anyone say he experienced same sort of the problems?
