I think it is a glitch. A few others have had the same or similar issues.

About once a week, I get ads when logged in.

I get ads alot, I figured that was a glitch. Glad the rating thing is a glitch, maybe they'll fix the way it's set up while they're fixing the glitch.(you remember my post about the dropdown star rating menu?... slide up would be better, or move the dl button...)
I also noticed the edit button has been lost again... Wulfn1 waits patiently to rate Kitty's new xp blind..

ooh edit button's back.

I havent been able to vote in over a month, nothing to do with cookies....at least here   

Yes, it happens lot here too as of last month even with full net cache clearance.
When it happens all browsers behave same so glitch not in users' computers necessarily.

Also my address keeps getting changed and not by me it alternates between IR and IS but never the correct IE. I don't want to be Iranian nor Icelandic just Irish.
I often reset it to correct IE but next day it will be back wrong.Tried emailing support but said issue fixed but it is not.

Steps to make sure all the cookies and temp files are cleared.

1. Log off of WinCustomize
2. Close all browser windows
3. Open a new browser (do not go to WinCustomize or login)
4. Clear your cookies & temporary internet files
5. Close all browser windows
6. Open browser
7. Go to WinCustomize
8. Login.

I was having this problem and all I did to fix it was run CCleaner.

Ccleaner does all that, I use it daily.. doesn't fix the not being able to vote problem.

As a matter of fact on a clean Vista install, first time visit to WC, using IE7... I couldn't vote, has to be something else.   

Not being able to vote isn't going to kill me but it sure is irritating some other folks I know. It's not cookie related.

Highlander,

If I try to buy anything at present I am set to Island, Iceland.
I reset it back to Ireland on My Account page but within a day it always reverts to IR or IS.

Present View

Yes, Cool Bundoran is Co Donegal but nicest in the summer like most of here.
Not been to Scandinavia yet, well just Iceland which I loved even the Black Death.

I know; I immediately change it back to Ireland, I save it as Ireland and it reverts to Iran or Iceland within a day often within seconds - what you see is after an immediate save, that is why you see "updating" on the pix and my highlighting on Iceland after saved it as Ireland seconds before. I save it so many times as Ireland but to no avail I know how to fill in forms but if I want to buy stuff on MC here it has to be within such a small time frame when it says Ireland or the card will be rejected for incorrect address. I know how to fill forms and in which country I live except for odd time I get poured off plane at Tulla.
