Google Chrome browser and Yahoo and MSN email accounts

I have been using the Google Chrome browser for sometime now and over the last week or so, I have been experiencing few issues when I access Yahoo email and MSN email accounts.

While accessing Yahoo email account using Google Chrome browser,  the drop down list of contacts is not appearing.  It is a pain when you have to pick the recipient's name using the insert address option.

While accessing MSN/Hotmail account using Google Chrome browser, the cursor is not even moving to the body of the email where you type the contents.  

Is it a one-off issue or a known problem with Google Chrome.  Does anybody faced this problem and know of a solution to overcome this? I can imagine that Microsoft and Yahoo doesnt want to allow Google Chrome to become popular.  Of course, yahoo doesnt have a browser of its own.
