I have tried all the usual methods to reset my fill & font colours back to
the default pallette but they just won't reset.

Tried the tools, options color reset - doidn't work
Tried to copy the colrs from another workbook but as soon as I opened the
workbook that had the palette that I wanted to change it would change all the
other default palettes that were open over to the new color palette.

Please help, very frustrated.
