Erel, I presume that you are referring to the loading/saving of the xml data, rather than the internal table representation.
Klaus: It seems that the scrollbar control available in ControlsEx.dll might be a workaround... if the change in column width can trigger an event so that we know when to add the control, or we accept that it needs to be there all the time & for every table event we bring the scrollbar to the front, hiding the real one if it's being displayed.
Haven't played with it yet, nor thought through the maths - that has to wait until we can tell if the total table (column) width has changed.
