I think I'm seeing the same thing on Linux with the 8.5a2 release. I have a utility procedure that does the same thing as ScrolledWindow, i.e., only draws the scrollbar if the text goes beyond the visible window. Now if I just output the arguments for every call of yscrollcommand generated by a text widget, it can be seen that sometimes they are not 0 and 1 when dragging the border even when the text is nowhere near filling the whole widget. This tends to happen when the last word of text is being wrapped onto a new line. If this call causes the scrollbar to be drawn, the textbox will be made narrower to accommodate it. This will generate another yscrollcommand with args 0 and 1, causing the scrollbar to be removed. An endless loop and shimering display can result. Hope this is of use --Jasper On Tuesday 19 April 2005 14:02, Alastair Davies wrote: > Thanks, Alan, for pointing this out.
