Jasondows is a computer program made by Jason Fox. It's a play on Windows. In order to prevent his family from finding out what he was doing, Jason used a code name: "Homework". Jason made it incredibly hard to uninstall, with a bunch of bugs. The next version would have corrected bugs and a new batch of bugs, and so on.
Unfortunately (for Jason at least) Windows 98 shipped before Jason could ship Jasondows- thank goodness for the rest of the cartoon world.
