I've got a rather large set of tabs using Conditional formatting, all created used with Excel 2010 (yes, I know, it's old)...when opened with the latest version (2016?) some of the formatting no longer works properly. Is this a known issue? Can it be from the shear number of formatting and conditions?
Thanks for any help! I will probably move the development platform for next year, but I'd like to hold off this year in spending any capital for new gear, updated software, etc.
