Background is white blank when I try to add anchor link in IE10

Hi All,

I am using IE10

Actually I Integrated  CKEditor 3.6.2 in my sakai application.

When I try to add anchor link in IE10,the background functionality goes to white color

I have tried with X-UA-Compatible=IE=edge  property but no use.

This functionality is working fine in other browsers even IE8 and IE9

Please go throgh the attached screen shots.

Can any one help out 

Thanks in advance.
