why yahoo chat wlindows do not properly close when I actually close them?

I use yahoo messenger 10. recently I came across a problem - I cant close a chat window properly. in the sense the window disappears when I click on 'X'. but when I restore the minused main window (home page) all the chat windows I might have closed till then - be it from contact list or from unknown people, appear at once on desk top along with them home page. dont know why this problem occured. will some one help me to solve this problem?

It may be a browser problem
Download 'ccleaner' and run it through a couple of times,using the factory settings and the 'Run Cleaner' control until 0 bytes are seen to be cleaned following a scan
Run the 'Registry' from the left hand toolbar but 'Save' any changes after opting to 'repair' errors.Never make changes to your Registry without saving the information.
