Hi J Chokshi
One way is to rename your xlb file
1) Close Excel
2) Do a search for .xlb in Windows (Use: search hidden files and folders)
3) Rename or delete the .xlb file or files (In 2002 the name = Excel10.xlb)
4) Start Excel
Deleting the file or renaming will do no harm to your system
Excel will create a new file for you. (You lost your customization remember that)
If you make your own toolbars or add buttons to the others
this file is important (backup it so you can restore it)
