BrowsePlus: Firefox, Explorer close when I press "Attach"

Hello,

Today when I tried to attach a file I was offered the new BrowserPlus. I selected "maybe later" and chose not to install BrowserPlus at that moment. After that, I pressed "Attach" again to select my file and the browser closed unexpectedly. I am using Firefox 3.5.5 under XP. I have tried several times, and both Firefox 3.5.5 and Internet Explorer 7 now close immediately after pressing "Attach". Remember I chose NOT to install BrowserPlus.

I logged in with a different yahoo acount, tried to attach a file, and again I was offered BrowserPlus, I declined, and now every time I press "Attach", both browsers will close unexpectedly with this different account. I can't attach files anymore with any account. I have gone back to Yahoo Classic, and attach works fine.

Whenever I restart Firefox after it closed unexpectedly, it won't restore the previous session unless I deselect the tab where I was using Yahoo Mail.

Lloyd or anyone else, may you help?
