Working with XL

Prior to SP3, an embedded XL spreadsheet could be re-sized, in respect of what part of the sheet was displayed, by clicking and dragging the borders. Post SP3 that functionality isn't there. There must be some other way to set what part of the spreadsheet is displayed, but I cant work out how. Lets say the spreadsheet contains 60 rows, but I want to display only the first 30 on a sheet. How do I size the spreadsheet to do that?
