IE8 fckedit2.6.x Not compatible _ page Editor

After the grab test, the Fckediter object did not submit any data at all
After multiple browsers (Ie7,ie6,mathon), it is found that this problem only appears in IE8
The source estimate is that IE8 has a resolution problem with Microsoft's AJAX. NET 2.0 version
The problem features are as follows:
The system is generated by the MasterPage page, which is placed in the Fckediter control
Use Ajax to include the Fckediter control;
The first normal access to the page, Fckediter can submit the data normally, but the submission of the refresh after the new data submitted to the fckediter of the data can not be submitted, or occasionally can be submitted;
No script error prompts, no server-side code exceptions and errors in the commit process;
Ie6,ie7,mathon under the test of the same function module, can be used normally;
The use of IE8 so-called "compatible page" function can not be normal submission of data;
Upgrade Fckediter to the latest version the problem remains;
Search the network, found that some people before the vista under the IE7 and independent IE8 Beta2 appeared under similar circumstances;
Because other versions of the browser are working properly, you can confirm that IE8 has compatibility issues and that this compatibility issue is unstable;
To sum up please do not blindly upgrade the system to IE8, whether the client or the corresponding server to meet the "compatibility."
