Hi,
While I was testing the file uploading feature in wordpress 2.0.1, I found a problem with inserting the documents link using "Linked to File + Using Filename + Send to the Editor"
By scanning "inline-uploading.php" file, I found the following in the line 262
----
...
[code]
ab[{$ID}] = '';[/code]
-----
After replacing {$filename} with {$attachment['guid']},I am able to link/insert the document file link correctly using (Linked to File + Using Filename + Send to Editor).
In case anyone having the same problem, try this and see if this fixes the issue that you are having.
