Problems with auto-show

I have lost track of what all the XEmacs mailing lists are for. Here is a bug report. I hope I have sent it to the right list. The auto-show mode that does automatic horizontal scrolling has problems with toolbars. Running the following code with "xemacs -q" shows the problem: (progn (insert "123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890") (set-specifier right-toolbar-width 40 'global) (set-specifier right-toolbar '(nil) 'global nil)) When you move around the buffer scrolling takes place even though it is not necessary because the lines are not truncated. The problem lies in the function auto-show-truncationp. It seems part of a general problem in XEmacs since toolbars, glyphs and variable-width characters were introduced: doing calculations with numbers of characters when you really need pixel values to do it right. --- Alastair P.S. This problem occurs because I use the right hand side for mode local toolbars and keep the top toolbar for the global functions. Is this not a better way of better way of doing things?
