Excel 2007 with Vista.
The look of my worksheet has changed! It looks like a 'minimized' sheet. And, I have lost the horizontl scroll bar and therefore I cannot get to the other worksheets in the workbook.
I went to Excel Options > Advanced > and both, horizontal & Vertical scroll bars are checked. How can I fix this problem.

While Excel will be maximised, the worksheet itself sounds as though it is minimised.

On the worksheet (not on the main Excel page) use the cursor on the worksheet title bar (not the Excel title bar) and drag it until you can see the minimise/maximise/x on the worksheet itself, then maximise the worksheet, which should fix the problem.
