Excel 2000 => upgraded to 2003 and Bar Chart Pattern disappeared
 

I have a bar chart composed of two bars each with a stacked series of bars.
For one of my bars one of the stacked points was a pattern fill (slashes).
Since my upgrade to Office 2003 the pattern fill for this one stacked bar has
disappeared.
I've upgraded to Office SP2 and still cannot set my fill pattern. I have had
to set the fill to color white until I can get this pattern back. I have
noticed that the Sample preview pane is not set when I select the pattern
fill, gradient fill, etc.
Is this a known problem? And is there a work around?
Thanks,
