Floating Button - Possible?

Is it possible to force a macro button to stay visible, or float, when scrolling around a spreadsheet? I would really like it to stay visible relative to where I place it in the work area.

If so how do I do it?

If not, how do I save a toolbar that will only be used by the Excel file for which I create it? In other words not stored in:

C:\Documents and Settings\Username\Application Data\Microsoft\Excel\Excel11.xlb

It needs to be contained within the workbook and close when the workbook is closed.

To have the command work only with that workbook, then you would need to include the code in and auto open

Sub AutoOpen()
'
'your code here
'
end sub

however you will also need to have a auto close sub to remove that macro from the command bar

sub AutoClose()
'
'yourcode
'
end sub

another easy way would be to have your buttons on the top rows of the spreadsheet and the freeze the panes this will allow you to scroll around the spreadsheet and the bar buttons will alwasy be seen.
