I have a similar problem. I have several worksheets open in my workbook. I
created a new worksheet via Insert Worksheet command. I want to rename the
new sheet (i.e., using all alpha-chars) and now I get the

'Microsoft Excel Error while renaming a sheet or cart, you entered an
invalid name.' error message

I've tried all combinations and possble sheet names but I'm in a error loop.
Only option looks to be to kill Excel and start over. The recommend option to
save the file and reopen it is grayed out.

Oops, cant exit ether, I get a 'Microsoft Excel Cannot quite Microsoft
Office Excel 'message. Never seen that one before.

Could this be related to the Microsoft Excel patch put out for 2003 a few
weeks ago?
