I use various excel worksheets throughout the day, and one of them is
experiencing an issue that the Minimize, Restore and Close buttons do not
show up when the workbook is loaded.

Just for clarification these buttons are the standard buttons at the top of
every window. I have tried adjusting the security settings and I also
deleted the temp files that were in the same folder, all with no success...

Any suggestions will be greatly appreciated.
Thanks In Advance,
Charlie
