Why does computer screen turn big when I click on limewire?

So when I double click on limewire my computer screen turns black for a couple seconds, then everything on the screen turns huge. I'm not sure whats going on. But I want to fix it but I don't know how. Oh and it stays like this even when i turn the computer off unless I go into display settings and change the size. So if anybody knows what I am talking about that would be great. Thank you :]Why does computer screen turn big when I click on limewire?
you can uninstall and reinstall limewire.

But....I would do like corey says, scan for spyware...limewire is KNOWN for it.
