Mac 'Mail' replying problem...

I have had my MacBook for about 1.5 years now and it has always had this problem but it's really starting to bug me now.

I use 'mail' as my email program...

When i reply to some people's emails all previous replies / text below disappears. I have changed all possible settings in prefences but nothing makes a difference. Sometimes when i forward emails to people they receive a blank email. Its really difficult when trying to do a deal via email as you have to keep ALL corresponding emails rather than just the last received one that has all the replies below...

Please please can someone help

You just have to turn quoting on. Mail -> Preferences -> Composing

As i said above... i have tried all the different settings in preferences.

It only happens sometimes when replying to certain people. When i reply to some people (who work for the same company as me and therefore have the same email addresses) i can see whole replies / conversations... but other people (who i also work with and therefore have the same email addresses / server) i can see nothing!!!

I don't get it... do i need to re-install mail? What do i do? :-S

As i said above... i have tried all the different settings in preferences.

Famous last words...

What happens when you highlight the body of the message you're replying to, and then hit Reply?

Nothing... still doesn't show up on replies.

When i am writing my replies i can see all the below text but when they receive it there is nothing below.

I run my hotmail account through mail (as i have several email addresses) and 98% of the time i don't have the problem with my hotmail account. Its mainly only with one of my accounts. Could it be the server? I bought this up with our hosting company and they said its nothing to do with them. They are not a big hosting company so i do get good personal help as opposed to a different person in a big company.

I really hope someone can help...
