GMail isn't an email client, (also known as email software). GMail is a 'web-based' email service where you manage emails through an internet browser.
It is possible to arrange for GMail's emails to be sent to an email client which is installed on your computer. But you need that email software to be installed before that can happen.
Common email client software applications are Outlook Express, Outlook, Thunderbird, Windows Live Mail, Eudora, to name a few.
Which email software do you have installed on your two computers?
You mention GMail's Notifier. As far as I am aware this is an application that alerts the user when new email is waiting to be read. It isn't email management software so I assume you still need a browser to read, manage and reply to emails. If I am incorrect, can you supply a link to those directions you mentioned?
Just so you know, Windows 7 HP 64 bit and Windows 7 HP 32 bit should not show any differences in this respect, or in most others. You would rarely see any differences in performance or use between the two.
Can you describe what happens, what you see, when you use this "Send to" option on your Dell machine? What is the difference when you do this on the Toshiba? This is what Jimmy was asking. What happens when you select that option?
To give you an idea of the problems you may be facing with this, goto Start then click the "Default Programs" in the right hand column. A window will open with 4 options. Select the first, (Set your default programs), and see what is listed. A new page will display showing default applications. Are any email applications listed?
Go back to the first page, (the Back button), and select the last option, (Set program access and computer defaults). A new window will open.
In this new window you have 3 choices, Microsoft Windows, Non-Microsoft, and Custom. Explore all 3 by clicking the double chevron down arrows for each on the right hand side. Do you see any software applications selected for Email?
Before web mail all Windows computers need email software to be installed on the system to manage emails. With the growth of web mail there has always been problems configuring Windows to accept web mail as a 'default program' because web mail is not a program. It is an internet service.
