I just received a new factory-imaged HDD with Windows Vista Home Premium and
installed my copy of MS Office Professional 2007.

Upon working with a one of my Excel files, I wanted to select a number of
non-adjacent cells to format identically. However, after I right-clicked and
applied preferred formatting, it was only applied to the last set of cells
selected.

Performing this action again -- while holding down CTRL and selecting the
data -- Excel would only recognize the most recent set of cells and not the
total number of cells. But, if I selected one set of cells, press the CTRL
key and select the next set and continue this process (let go of CTRL and
depress again prior to selecting the next set of cells) everything works
fine.

This is not "normal" functioning of Excel as my system at the office works
as expected -- to select non-adjacent cells you keep the CTRL depressed.

Does anyone have suggestions on how to correct this issue?
