Problems with Hotmail-help!!

[zzzuppp]

My partner-using the same Mac-is having lots of problems with her Hotmail a/c.She can't send emails or attachments without getting frequent 'Error' messages.Often,logging in,all her messages have vanished.I too have a Hotmail a/c and mine works fine.Is this a problem with Hotmail/my partner's prefs/or something else?
Is there something I can do with cookies/caches? If so,how??
She's tried changing Browsers-we have Mozilla,IE and Safari,same problems each time;which suggests it's a Hotmail problem-but how come mine is OK?
Any suggestions gratefully received.

PowerMac G4 OSX 10.3.4

If she logs into her Hotmail account from your Mac does it work or is it still screwed up? If her's works fine on you computer then it's an issue with her computer. If her account is still screwed up on you computer but you account is fine then it's a problem with her Hotmail Account.

EDIT: Ok stupid me, you are using the same computer. Do you have seprate account's on the mac, or do you share one? If you have seperate accounts try creating a third one and try both your hotmail accounts.
