I upgraded from 10.6 -> 10.8. In 10.6, when I opened a new window (apple-N), it just opened. Now it opens with a ~1/2 second delay, because of this annoying special effect where it grows out of the center, rectangularly. The same thing happens when you empty the trash. The dialog box grows out of the center, instead of just appearing quickly. It's annoying because it makes my computer feel slower. It effectively is slower if it makes me wait longer to read a dialog. Is there some defaults settings I can override to remove this? Anyone know how to remove the special effect? Or speed it up.
