Can't input by ...

Now I can't input to blog form in Japanese, caused by...
マックで文字が入力できない(教えて！goo) I think the blog service provider has to provide HTML management form in order to avoid this issue. If Oshiete-goo's information is right, HTML style security level is more higher than FLAHS style. It means, to prepare HTML page is not only for troubleshooting. It's also providing the higher service against security risk.

Its too difficult for me.
