I can generate and send mail without difficulty using the 'Create Mail'
button. If I use the 'Reply' button to respond to incoming mail, I receive
an error message, 'Outlook Express has encountered a problem and needs to
close.' Usually this message appears immediately but sometimes it appears
when I am typing the reply. OE shuts down.

The error signature info. gives:
AppName: msimm.exe AppVer: 6.0.2900.2180 ModName: ntdll.dll ModVer:
5.1.2600.2180 Offset: 00010f2b

I'm using XP which is fully up to date.

If anyone can understand what is wrong I would welcome some help, with thanks.
