I want personal help, the articles I see do nothing to fix (Not Responding) slowdowns with virtually every click.

Question

It takes about 37 seconds to delete a message. Sometimes the screen goes white, but I can see text in a light yellow shadow. My gmail accounts are quicker but my @SHAW.CA account is very slow - unfortunately it is the first listed (can I move it to the end of my 3-email account list?)
I am very, very frustrated by the slowness (it was not that way before) my computer is new & has an Intel core i7 - other progs run fast and smoothly (big fan of Firefox).

Windows safe mode is what I would select at this point.
Standard safe mode text follows.
To diagnose problems with Thunderbird, try one of the following:
*Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
*Restart the operating system in '''[http://en.wikipedia.org/wiki/Safe_mode safe mode with Networking]'''.

; If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.
