Hi Bijo,

The problem is most likely due to some global CSS class for A tags which is applying font-size to the links in the content area. You can fix it by setting the CssFiles property as shown in this help article:
Content Area Appearance Problems.

Hello,
             Thank you for your reply. I had tried with the mention link of the CSS class.  I did n't see any A tag class in Editor content area.
Then how the tag class will effect for the <a> , after inserting a document.
But it fine with IE and not with Chrome.


More over i have noticed one more issue in Chrome. ie, If we type one word say' Administration' , then we try to change the font size , 
say i need to be 7 th  size , it  becomes as it is. means i got bigger size(7).

But , iam trying to change it to another size (4) , it won't be. The word remains in same size ( 7 th) .
What to do. ?

eg. <font size="7" face="AZBY">administration</font> ( i got , when i try to change the font size to 7 )

Can you say, what is this face = AZBy  ?
Thank you

Hi Bijo,

RadEditor Classic does not support the modern browsers and the reported problem could be due to that. Its development and support is discontinued since 2008 and for this reason it is highly recommended to migrate to the new and much enhanced RadEditor for ASP.NET AJAX. Upgrading instructions are provided in the following help article: Migration from RadEditor Classic to RadEditor for ASP.NET AJAX.

The face="AZBY" problem is also fixed in the new version of the control.

The only thing that you can try before considering to upgrade is to replace the FontSize tool with the RealFontSize tool of RadEditor Classic and see whether this will fix the font size issue.
