On the lighter side of things, I felt like sharing some of my annoyances.
1. Programs that have a non-critical event (ie not a catastrophic failure) that grabs focus when said program isn't the current active window. *looks menacingly at his toolbar* If my pc isn't about to melt down, then you stay out of my workspace unless I deliberately summon you. (or at least have an option to control said behavior)
2. Webpages that set focus to the first editable control. Pages don't load immediately every time, often some graphic is holding up the process, but I'm already off to the races typing. Then in the middle of my typing POOF! My cursor jumps up the form. I have to delete out whatever I was typing from the first control, and go back down to where I was to continue.
3. Those ads that roll right across the text you're reading on the web. (Yeah, there are ways to block them, but man, what sadist thought up these types of ads).
4. #3, with sound (ever have your speakers up fairly loud from a recent gaming session and have an ad with sound scare the living s--- out of you?)
5. Javascript, because it has the absolute worst error messages I have ever seen.
6. People that think that because I'm a programmer I can fix their pc hardware.
