worksheet tabs missing

[shakey]

I recently changed from Excel 2003 to 2007 office standard. I have worked
this file in the new office twice but now problem.
I opened file with two worksheets and updated one sheet as well as changing
the number of lines to print in a macro. Went to change to other sheet and
can not find Tabs that were there. It appears that bar is missing or has
been replaced by the status bar.
Please tell me how to get my sheet tabs back.
