I have a spreadsheet that has several VB buttons with macros imbedded in
them. Sometimes when I open up Excel, the buttons disappear and all I am left
with are shadows of invisible buttons. I am able to click on the 'invisible'
buttons but cannot see them. This happens off and on and I have not been able
to figure out how to fix this.

I am running Office XP on a Windows XP Pro operating system. Any help in
this regard will be appreciated.

Thanks,
Jay
