You are being very vague. I can only iron out problems if I know about them and can reproduce them so please be specific in telling me what steps I need to take to see the problem.
in this case it was the mojoPortal site that I found it
I don't have any idea what you are talking about, the addthis bookmarking link is a good distance from the signout link on mojoPortal.com, it does not interfere with the signout link in either Firefox or IE7. Have you tried refreshing the page in your browser? Maybe you have some old version of the css in the browser cache.
but the problems in IE7 are just as much a problem. I think sometimes the run to fast to get new releases out and consequently have not ironed out problems
Thats not a very kind assertion to imply I must be rushing things when you haven't even made clear what problems in IE7 or Firefox. I cannot address general assertions of bugs I need to know exactly what bugs and how to produce them.
I test in Firefox IE7 on XP and IE6 on XP. I'm not perfect and there may be specific style bugs in specific skins but you need to be more specific if you want me to find and fix them. I "know" of some issues in IE 6 with some skins, but in my testing with IE7 on XP I am not seeing any problems with the skins. I use Firefox most of the time as my main browser so I think I would see problems there if they exist.
