Thanks Joel

I changed the security setting. I have not used macros and I don't see any
changes occurring when I open the file. When I open excel and select blank
worksheet, the Undo is still faint on the toolbar.

I will follow what you have given me.

VBA are macro programs that run within excel. The xls file may have macro
programs that you don't know about. I is best to keep excel in the Medium
Secutiry Mode that will prompt you when you open the file if there arre
macros and let you disble them when the file is opened.

to Change you security settings
Tools - Macro - Security - Medium

There is an explaination of each of the security modes when you get to the
menu above. I like to know when I get a macro in an xls file so I don't have
a low setting which will auctomatically run the macro. I don't want a high
setting that doesn't allow macro to run at all.

My undo button is on the toolbar but is faint. View menu Can't undo is also
faint. I tried deleting and custom addition of the functions and they show
active until I close the custom window. Reloading or switching users does
not work. I saw a question on this and an answer about VBA or addon could be
affecting. What is VBA? I am not a programmer. I did import a xls file
that I received from an associate and startet working on that. Could that
have effected the main program?
