On the screen click on the "handset" and should open a window to make a call, but the black window opens and nothing. This window can then as with any window close call but has only through the contacts. What's the problem?

What OS? Have you rebooted the device? Better yet, what exactly have you done to fix this yourself? Anything? Nothing? Asking for help is great but it's like a relationship, it's a two way street. Help us, help you by telling us what you may have already done.
