Test case:

• create a test topic, write a non-existing wikiword, save
• click on the question mark to edit mode of the new topic
• write some content, save, go back in the browser to the first test topic
• it will show the old, cached page with the link to the non-existing wikiword
• click on the question mark again
• in IE7 on Win2K, this will open an empty edit screen, although the topic already exists

I can confirm this. It was the same in 4.0.5. The cause is that IE caches the edit URL so when you click the same ?-mark again you get the same cached page again. And then you basically overwrite the previous version of the topic.

It does not help adding a random time stamp to the URL because when you go back with your browser the ?-mark link is still the same with the same time string so the browser will most likely still pick up the cached version.

IE 6 does the same!

And Firefox does the same.

There is nothing we really can do about it. To TWiki it is the browser opening an existing topic and saving a completely new version on top.
