Won't go back to the today screen

[ImCoKeMaN]

If this has been asked before feel free to send me a virtual smack, but i sure couldn't figure out any useful search terms for it. So anyway...I occasionally have a problem where my phone isn't happy about something and it will not return to the today screen. Is this a common thing? So far the only cure i've found is a soft reset (i guess a hard reset could work too =P ) It seems random when it happens sometimes after a call it won't go back even when closing etc. But everything else seems to work. I can open up other programs, the menu bar works, but it will never return to the today screen. I do have magicbutton installed, but that is about the only common thing i can think of that might be part of the problem. Ideas?!....
