In Win7x64, Google email in the form of HTML source becomes mangled in Office Outlook (which I've substituted for incompatible Outlook Express).
To replace Outlook Express, I first tried Thunderbird, and then Eudora. Only Office Outlook, which is part of MS Office, had all the functions and options of Outlook Express that I like, plus formatting and organization features.
I could use Web Mail with Gmail or ATT-Yahoo, to which I have access, but I prefer getting my mail to my PC and keeping it there.
