Save Logins Get Erased

This just started happening when I use N360 V6 PC Tuneup's "Windows Temporary Files" it has now started erasing login that that I want to stay logged into; for example my dual home pages my personalized  Google homepage and my personalized Earthlink homepage. Norton 360 did not do this till today. I tested the other setting with PC Tuneup and they leave those sites logged in. I do not want to have to us Identity Safe ever time I want to log in those sites or forego using the PC Tuneup's "Windows Temporary Files" feature. I using Window's XP Service Pack 3 and IE 8.
