I have a pretty complex workbook that is exhibiting some odd behavior.

On many pages of the workbook, with some consistency, when I press Pf9 or trigger a Macro that has Calculate in it the screen will present a partial view from another tab.  When this happens I can see part of the screen on which I am actually working and part of the data/view of another tab.  If I scroll down so that the other tab view is off the screen, and scroll back it will have corrected itself.

Sometimes this happens if I do a Save command as well, which I presume does an Calculate as part of the Save Function.

This workbook does have a lot of tabs but I've never heard of a limit that would cause this behavior.

Everything else seems to function fine, no impact to the data or the functionality.

I'm on Windows 10, Excel 2013.  Intel i7 920 @2.67Ghz. 12GB RAM.  64bit.

Thanks for any help!

Due to many requests and responses in the forums we can guess that this issue is related to the driver of your graphic card, it is not compatible to  Win 10.

Try the same workbook on a Win8.1 machine with same Office version.
