Shared Workbook Hell

Hi all,

It's been a while, I know. I've gone from working in a middle school to working for a university. So, as far as I'm concerned, I am still an edugeek.

We are having a problem over here with a shared workbook. When we try to open it, three out of the 5 sheets show only grey - no cells, no data, just the column letters and grey.

I know the data is still being read because the other two, readable, sheets are interacting fine with the data that's on the other, 'blank', sheets. We have tried everything to solve this, but haven't been able find a solution.

The problem only came about when I set the workbook to be shared. No-one has had any time to mess with it, so I know it isn't human error (except, possibly, my own).

Has anyone come across this before. Has anyone found a solution.

Thannks. It's good to be back.
