color palette permenantly altered
 

I've been having this annoying problem with color pallettes where one file
will inherit the color palette scheme if I open any other file after it. That
is, if I have one file open in excel with the default palette and open
another file that has a custom palette, the first file will inherit the
custom palette, often with illegilble results. Up until recently, if I closed
completely out of excel and reopened the file that had the normal palette, it
would then display correctly.

However, today, the same thing happened but the close/reopen excel strategy
no longer repairs the color palette for certain files. I tried restarting my
computer and going to Tools Options Colors Reset, with no success. I
might be able to reset the colors manually (very annoying), but I fear the
same thing might happen again. Is there a way to fix my problem, and if so,
is there a way to prevent excel from applying the colors scheme from one
excel file to another?

Thanks
