I downloaded yahoo messenger beta version for mac and when I click the file on my desktop nothing happens?

.Unfortunately there are some issues with Yahoo Messenger's compatibility for Macs presently. The only workaround at this time is to use Adium X for Mac: http://adiumx.com/ It is a free multi-chat instant messaging application which can connect toYahoo, AIM, MSN, Google,and more.

.Are you using window blinds or alien guise or some other window enhancement program? E.g. programs that add extra buttons like transparency and keep always on top or change the look of the windows in anyway (not including standard XP themes)

if so disable it and yahoo should work..

Do a search on http://www.wackyb.com/ for window blinds

This is sometimes a flash issue, make sure you have download and installed flash from Internet explorer (not any other browser)

This also helps.

Go for removal ofhistory of items on your search bar

On the right side of the bar before you get to the web search button click on the bar (you may have to click it a few times) will open a drop down box that will bring you at the front of items you searched for.

Place your mouse pointer over the first item and you will see it highlight. Do not click the item just leave your mouse where it is and hit the delete button on your keyboard. The item will vanish and the next will take its place and become highlighted. Just keep hitting the delete button and watch them go away.

This will work for any browser.
