XL Toolbox Undo Panic

Not sure if the screen shot will post or not… I went to the Misc… Add Water Mark and got and error
“XL Toolbox Undo Panic. Can not prepare Undo”…Object does not support his action (#455)

If I select continue anyway … I get an error has occurred… I did submit a crash report.

also got similar error messages with the ponit chart option.
