Have you got any default worksheet font format settings?
You can try right clicking on a worksheet and select copy formatting and applying it to the target worksheet.
Thank you your quick response! I tried copying formatting from one sheet to another, and I just tried clearing the formatting (Format-->Clear Formatting), no change either try.
Is one of them set to "entire view" maybe?
Thanks for jumping in! Both sheets are set to "Fit Width". We've played around with changing the view settings with no change.
