Windows 7: Windows Live Mail Annoyance

Hi,
I'm using Windows Live Mail Version 2009 (Build 14.0.8050.1202) as my email client but have an annoying problem.

When I receive an email and wish to forward part of the content in the body of the message, I find it difficult - and sometimes impossible - to delete unwanted parts of the message. Having selected the 'Forward' option from the menu, if I wish to delete some of the unnecessary content, which often acccumulates at the bottom of emails which have been forwarded a number of times, I select the unwanted content (Highlight it) and press the Delete key. Sometimes it does not delete and other times it does delete and the cursor immediately jumps to the top left position of the window instead of remaining at its original location - which is annoying if I wish to delete some other items near the bottom of the page.
I also find that it is most times impossible to delete content by just highlighting an area - particularly where there are blank lines in the content - and hitting the Delete key or Backspace key, to remove the selected content.

Sometimes, it is possible to move the cursor to different places within the content and press either the Del key or Backspace key and delete parts character by character, but there are often parts which just cannot be deleted by any means

I wonder if anyone else has observed this problem and come up with a solution?

I copy and paste for two reasons
I do not know if the origianl senders want their address sent to another and
to avoid the problems that you are having.

Thanks for your reply richc46. As a matter of course, I always delete any senders'. or other email addresses from all emails to which I reply or ones I forward. It's a pity that most users do not do so - it would help to reduce the harvesting of addresses and cut down the amount of spam rubbish which everyone receives..... Furthermore, it is just plain bad manners to forward other people's email addresses to all and sundry!!

I have used the Cut & Paste method, which as you point out, can get around the problem, but surely, being unable to delete content from a received email, which is to be forwarded, is a basic shortcoming of the program........ The problem didn't exist in Outlook Express which was a perfectly good and popular email client. Why Microshaft in their wisdom, decided to drop it from Vista and Win 7 beats me !! If it ain't broke - don't fix it!
I know that there are other email clients such as MS Outlook and Thunderbird, however, I don't have MS Office and I didn't particulary like Thunderbird.......

I have WLM on my portable Windows 7 PC so I only occasionally use the email program. I just tested the select and delete using the keyboard's delete key and it worked fine. However, I generally select and delete with the mouse; so I wonder if that would be a workaround.
