I just updated to the lastest 2.16 version of tinyD. It is also my first time to use the spaw editor. I seem to have some strange problem. Whenever I use the spaw editor to edit an article and click submit, I got the next page saying the database is updated successfully but the page did not redirect. I have to click the link on the page to return to the admin site again. The page source actually contains the correct HTML meta tag for redirectling the page but the browser simply did not redirect. After this happening, all other modules in my system which displaying the intermediate page also stop redirecting until I restart the browser (I tried both Mozilla and Firefox)

This seems only related to the spaw editor. If I use the normal editor I do not have any problem.

hmmm.
It sounds curious.

Have you tried the older version of SPAW including TinyD <= 2.15 ?

If it works fine with your environment, it might be the bug of the latest version of SPAW.
