Hi, all.

My sincere thanks to David (G3YXX) for finding out the reason why I was 
having trouble changing sheets in an Excel file using the control page-up 
and page-down commands.

It turns out that the multi-sheet EOC message file that I had been trying to 
work with was protected, and therefore, wouldn't let me switch from one 
sheet to the next in the normal fashion.

He discovered that I first need to "unprotect" each sheet by going to the 
protect-unprotect option in the tools menu.

Once that's done, control page-up and page-down will work.

For a while there, I thought I was loosing my mind, but now David has 
brought some level of sanity back into focus.

I am posting this info both to thank Dave, and to help any others who might 
experience this problem in the future.
