Outlook Express crash on user switching

I have a windows xp home machine and it crashes frequently when i switch users. It will work fine when it automatically goes to a persons inbox but as soon as i tell it to switch to a different user, it crashes. I doesn’t always crash the entire computer, sometimes it only crashes the internet and anything related to it wont work until I restart. My windows xp pro machine has absolutley no problems what so ever with it. Is it just xp home? Thanks.
