This chapter is all about warnings—warnings you can use each and every day. Ready? First, don't ever stick a screwdriver into a light socket. Oh yeah, and don't put your finger in there either. Of course that's not the kind of warning you were hoping for, is it? I'm guessing that you're more interested in Photoshop warnings, aren't you? Okay, fine. I'll leave my important everyday warnings for another book.
I gotta tell you, this chapter was a lot of fun to put together. Trying to force warning dialogs to appear is more challenging than you might think. And I'd like to point out that I had to force every single one of these dialogs to appear—not one of them appeared because I simply made a mistake. (If you believe that one, I've got some lovely land for sale here in Florida.)
Some dialogs are self-explanatory, others cause raised eyebrows, but many of these warning dialogs can be avoided. Here are the most common warning messages you're likely to run into (and a few you may not see all that often), the reason why the warning appears, how to fix the problem, and—when possible—how to prevent the warning from appearing in the first place.
When you encounter a warning, use this chapter as a visual index to track down the dialog. Many warnings look similar, but as you scan through each section, I'm sure you can find the one you're looking for (or one that's very similar).
As I mentioned, some of the warning messages are pretty self-explanatory, and some of the solutions to fixing the problem or avoiding the warning may seem pretty obvious. My goal here is to cover all the typical warning dialogs—from the Homer Simpson “D'ohs” to the “Oh, that's why.” It's also important to note that I didn't bother going through every possible warning. For example, if you've seen one “this-layer-is-locked-so-your-tool-won't-work” warning, I don't think you'll need to see the same warning dialog for every single tool.
