Different options to hide tabs in Excel
 

Hey all, I know of two ways to hide the tabs of worksheets in Excel (I'm
using 2003).

1. By going into "Tools"-"Options" and then unclicking "Sheet Tabs"
2. By going into the Sheets (whose tab you want to hide) and selecting
"Format"-"Sheet"-"Hide"

However, I've been looking at this one excel file and I can't figure out how
it is hiding its tabs.

It doesn't seem to be hiding the tabs with either of the above two methods
since:
1. The "Sheet Tabs" checkbox is clicked (i.e. they should be showing
according to that). Also, I've tried deselecting that checkbox, clicking
"ok" and then tried going back in and selecting it and clicking "ok" and
still the tabs don't appear.
2. I can't unhide the sheets under "Format"-"Sheet"-"Unhide". Also in the
VB code that shows the sheets, it just uses the "Select" method of the sheets
- which wouldn't be possible if the sheet was not visible (i.e. you would
have to make the sheet visible first).

I think this excel file may have been created with an earlier version of
excel and therefore it may be using an alternate means to hide the tabs.

I should add, that no tabs control is even visible in the excel workbook -
i.e. regardless of what sheet you are on - you can't access the tab control
on the bottom of the page. Which matches the criteria of the "Sheet Tabs"
checkbox - but it is definitely checked.

Thanks for any suggestions as to how these tabs (specifically the whole tab
control) is being hidden.
