Microsoft Ajax tool kit Problem

I have used Microsoft Ajax tool kit controls like auto extender, extender calender and flyout in my project.


For using ajax functionality i have used ASP.NET Script Manager but while using Script manager .NET Framework generate script resource file of size 255 kb on client side for ajax functionality.


I have solved this problem by using toolkitScriptManager that inherit ASP.NET Script Manager and its reduced around 300 kb of script resource file but while i m using property CombineScripts = "true" .NET Framework combine script into one script resource file and compress it also but a java script error occured that "AjaxControlToolkit" is undefined in IE7.


any one have any better solution to minimize Script Resource file.
