"I not only allow session cookies in Firefox, IE, and the AOL browser but I allow other cookies as well including 3rd party cookies. Then I clean them out from time to time--and in this case that is what got me into trouble with the board settings."
First of all you keep talking about Rootsweb Help Desk. Who cares other than you? Most of us here are Acom subscribers, including yourself no doubt, and offers of workarounds are on that basis. That is, *not* going through the RW portal to the message boards, but rather the Acom one.
Secondly, you have identified two actions in the quote of yours above re what caused this problem for you. And note that with the same problem in FF I did nothing but still got it.
So you only allow session cookies (while I allow persistent), and you cleared everything.
Despite allowing persistent cookies, or at least not using a one button delete in FF, I do manually delete lots of cookies all the time, but not the Acom or certain other ones. However of course lots of them expire eventually on their own.
I would like to suggest that you try once more in Firefox with the exact steps below in this order:
1) Sign off Acom and navigate to another site.
2) Delete all cookies and history (I also have a flash cookie cleaner for FF that auto deletes on close), and enable persistent cookies.
3) Close and restart FF
4) Navigate to a message board *through the Acom portal* and some thread and choose flat view.
5) Log into Acom.
6) Go to My Acom board favorites and set to how many you like to view at a time past the default 10.
7) Close FF normally.
8) Open FF again and see if your thread view and number of boards in MyAcom stuck.
The point of the above steps is *not* to use the RW portal and to enable persistent cookies.
Also note that I still use XP SP3. With Firefox though I doubt it matters as to OS.
Finally it should come as no surprise to you that Acom is not addressing this themselves or via RW. The have a low commitment to quality control, the consequences of which (high customer churn), they seem to be able to overcome with cuddly marketing hype. Would you even risk donuts to dollars that they check all the major OS versions against the more recent versions of each browser to insure consistent behavior?
