Due to several comments about how much people hate this thing, I've pulled together a very rough, very simple add-in.Â It's goal is to disable the Compatibility Checker as much as possible.
I'm being quite up front that this was a VERY quick job, not well tested, and it can certainly be improved.Â But it's a start.Â 🙂
It will disable the Compatibility Checker on all files that have already been saved at least once in Excel 97-2003 format.Â New files are a little more problematic, though, as they seem to kick off the check even if you tell it not too.
You can find the add-in on my main site.
Oh.. and comments/improvements are welcome.Â Please post them here.Â 🙂
