No VBA and yes the same version. If I take the same file and delete the last sheet the file size reduces from 4.45MB to 388KB. If I try to delete a row in the last sheet it will lock up my computer. I running excel 2003 on a IBM T43.
My data ends AF 41 and when I hit CLT END it goes to AF41. I've tried deleted all of the data, formating and the file size still will not reduce. If you scroll the mouse the spreadsheet seems real slow.
