First of all... thanks for this plugin!! I have tried others... but this one is THE plugin;-)
However (... I know... but you know.... it's always like that;-)), I'm using it with an other plugin (WP-DownloadManager) which is a simple (but great!) download manager.
This plugin allows two types of download methods: "redirect to a file" or "output File". The second one will, as far as I understood, force the download (*) so that the browser will not open the file "inside itself" (as the first option), but rather will open a window to "Open with" or "save" file's options. In this case the file will be corrupted (by your pluggin :-( ), and guess what? This is the way I would like it to work;-)
Not mentioned, the files to download (in my case) are pdf files.
(*) extract of the code: header("Content-Type: application/force-download");
The first method of download is working, so no panic, I have a work around. But as it's the only problem I found with your plugin, and as it "sounds" to be generic, I wanted to let you know it in case you can have a look at it.
Well, it's almost all, please let me know any further details.
Thanks in advance, and again thanks for your plugin!
