You mean this one right?

that is "normal"... it is a poorly named dialog, but it will come up everytime you start Electrum... it is really just the password entry screen for your wallet

Not sure why it is "hanging" after you enter your password though... is your wallet really massive or something? Do you have thousands and thousands of transactions in it? Did you set it up to put your wallet on low speed storage like a usb thumb drive or something? or maybe it is a hardware issue and your hard drive is failing?
