In IE it works because IE sends the complete directory information about a file with an upload. This information is used to produce a file on the _local_ filesystem.
This only works on IE. It won't work if you (re)move directly after upload. It does not work in firefox or any other browser.
The solution is to make the editwizards produce an url _on the server_ to the uploaded, but not yet put in a node attachment. This could be done using the 'FileServlet' which is available in mmbase-resource.jar (of mmbase 1.9).
