Hi,
I have a series of charts updating from a simple table with various
formulas. All has worked well for a couple of months when this morning all
of the charts were grayed out. They are now covered by a shaded gray area,
I can select the chart with my mouse and the chart will display normally,
move the mouse to a new cell and chart is covered over again.

I'd appreciate any ideas as to why this is happenning, I have moved the file
to a different machine but have the same problem.

Thanks,
Mickey
