IE fails the _tests/manual/fckeditorapi

[alfonsoml]

IE doesn't fire the unload event of the inner frame until the whole parent window is unloaded. Simplified testcase available in [365].

This means that even if an instance of FCKeditor has been removed it's still available in the FCKeditorAPI.__Instances object.

Actually, it is not the IE doesn't call unload. It instead "delays" its call. It doesn't happen in the right moment that the window is removed, but a few seconds after it.

Just try it with _test/manual/fckeditorapi... you will see that if you create two instance, and remove one of them, the array will still have two instances. But, wait a little and click the update button again... wait again, and update again... you will check that, unexpectedly, the remove instance will be removed from the array.

I still have no idea how to handle this thing. Maybe a combination with "onbeforeunload", but we still have to investigate it deeper. Targeting to the 3.0 for now.

Yes, you're right. But it can take more than just a seconds, even some minute. I guess that they only do it on garbage cleaning and it can take a while.

For V3, we have implemented the "destroy" function to take care of this issue.
