Hi

I have this very weird problem.
I have a workbook with several worksheets, many hidden, several macro buttons, and some vba modules to do various things, etc, etc.

One of the sheets is basically a line chart with a few series (which change depending on user selection). Also on the sheet is a table to the right.
When I am in the workbook everything seems to work fine, and I can flick between sheets (using buttons), and make selections to change the chart, etc.

However - whenever I open the workbook, the chart size seems to have grown of shrunk relative to the page.
But the height and width of the chart are the same!!
Also the column widths are the same and row height. The table is the same size etc, and is in the same position on the page. Zoom is also the same. (90%).

I end up re-sizing the chart each time. But have the same problem when re-opening! (But not to 1 standard size - it seems to toggle between 2-3 different height x width's).

And yes I have experimented with the various 'Object Positioning' options (Move and sive, don't move and size, etc...) with no luck.

The only workbook 'on opening' vba actions I have are hide headings and view in full screen mode.

Any help is much appreciated. Thanks
