When the regular Photoshop does things like that, I reset the preferences by holding down the CTRL, ALT, and SHIFT buttons as the program is starting. This works in PSE also. You have to keep holding them down as the program starts. When the program has started, keep holding the buttons down and click on edit. Again, you keep holding down the buttons until you get a message asking "Delete the Photoshop Elements Settings File? When that comes up, release the buttons and click yes. This doesn't delete any of your presets or actions, but it does fix bad behavior in the program. I hope that helps.
