The file selection dialogue when an app wants you to navigate to and choose a file (attached) is too small (for me). It can be resized, but anyone know how to make the new size stick as default, if it's possible? Gotta be a registry setting somewhere at least, you'd think...
Try Method Two in this tutorial to see if Vista will remember how you have these windows set. After you do this, open the choose file window set how you want it and close it. When you open it again it should be the same as it was when you closed it. These windows may work on a per program basis, so you may have to set each one per program.
