Programs that Suck

Just thought I would start a list of suck programs that give me headaches, no particular order:

1. Wordperfect - Because it does not use the printer in a standard windows way, so I end up with every other program printing, EXCEPT Wordperfect. Heaven forbid they use Word, you know, since we have already paid for it and all our IT staff are trained on it, and 90% of people use it. I know, I made that last statistic up.
   

I will be adding to this list as more programs tick me off, and they will. Do you have any programs that make you want to pull your hair out? Let me know in the comments.
