System stop when sending e-mail with OE6

[benedetto]

Dear friends,
my system is WIN XP SP2 and I am using outlook express 6 as e-mail-program.
When I send an e-mail with attachements (documents, photos etc.) all the system stop and I must reset the computer. The program doesn't show any error message.After restarting the e-mail is shown as sent but I cannot restart the PC every time!
Please, help me.
Thank you very much.

Please provide a LOT more information, like  internet connection, ISP, malware protection being used, etc. See below.

Has it always been this way or did it just start? What about a system restore to a point before this began?

Does this problem happen with any and all attachments?  In other words, do small attachments, such as a single Word file, also cause this behavior?

You say "After restarting the e-mail is shown as sent".  Do the messages always, in fact, get sent?   Have you verified this with the recipient?

Now: the internet connection is an ADSL (called "broadband 2Mb" here in Sweden) and I have Ewido as malware program and AD-Aware plus AVG antivirus (free edition). These programs runs every week.
The problem came only circa 15 days ago. All the other programs run normally.
I have verified that the messages are really send.
The problem happen with all the types of attachements (word, jpg, excel and so on).
Many thanks for the help.

Well, you might try these steps as a beginning point.  Run Windows Disk Cleanup, and then run OE Cleanup (Tools, Options, Maintenance, Clean Up Now).

Hi Soybean and thank you.
I  did as you said but when I open Tool<Options<Maintenance<Clean Up I find the choice between "compress the files"( it is already selected) and "cancel all the received messages"(and I don't want to do it !). What have I to do now ?
waiting for your kind reply.
