how can i let fck do not replace < to &lt; in any case

my english is not good.so i am not sure if the title i use can express my question.

when i am using fck in normal mode,i type in html code like <#TEMPLATE_INCLUDE_DYAD#>.it will be changed to <p>&lt;#TEMPLATE_INCLUDE_DYAD#&gt;</p> in the source mode.

i don not want this happen.what should i do to stop it?

i have tried add FCKConfig.ProtectedSource.Add( /<%[\s\S]*?%>/g ) ; // ASP style server side code <%...%>

it does not work.

thank you for help me!
