Powerpoint with Excel formatted information

My team has an excel file with Text and Icons in a status report format.
We use it to copy and insert paste into Powerpoint. After copying into
Powerpoint, I try to select it and edit but powerpoint gives an error that
says:

"There isn't enough memory available to read the Excel file"

Other team members use this same excel template and powerpoint and they can
edit the information after it is copied to powerpoint. And I can use their
files and they work fine. Only one team member has this issue so somehow
this person's excel file is using a massive amount of memory -- is there some
way that I can run something to see what is in this file that uses up all the
memory? What typically causes a memory problem in copying Excel into PPT?
We are using 2007.
