I used to have this huge hunk-a-junk of a computer at work. It wasn't old, it didn't have outdated specifications, and it worked fine for 99% of what I wanted to do, but I was absolutely unable to get it to work with Microsoft Excel.
Whenever I opened the program, my computer would freeze. Whenever I tried to type in information, my computer would freeze. Whenever I tried to save my work, my computer would freeze.
There was just something about Excel that my computer hated, even though the program isn't supposed to be difficult to utilize.
