I had and really enjoyed using PHPStorm 3. Then I installed PHPStorm 4, and suddenly the editor no longer works the way that I expect. (I'm on a Windows Y platform.) Specifically, when I hit the DownArrow key, the cursor moves down one lne but not back to the start of the line. When I highlight something and attempt to type over it, I just get error beeps. And on and on and on. In short, PHPStorm has gone from a wonderful, useful tool to a pain in the ... . I'm sure I'm doing something wrong, but for the life of me, I've gone through all the settings, the manual, and everything else I can find, and I can't find what it is. Can anyone tell me how to get the PHPStorm internal editor to cooperate?
