Hello again, finding out that my message was finally posted twice. Here is some additional info.
Behavior has changed since last post and I can't figure out why as the code itself has not changed. Here is the log : uploader detected Flash player version 9.0.124, starting up... uploader is ready for use. File filters have been set to the following: *.jpg;*.png;*.gif : fichiers de type : *.jpg;*.png;*.gif Multiple file upload has been turned off. Mouse rolled over uploader. Mouse down on uploader. Mouse up on uploader. Mouse click detected, launching 'Open File' dialog. Browsing for a single file. Browse for file dialog open: User can select 1 file. Mouse rolled out uploader. Browse for file dialog closed The file queue could not be emptied since no files have been added. <--- New message FileID 'uploader9806_0' ('Attention.jpg): added to the queue. Queue upload started FileID 'uploader9806_0' ('Attention.jpg): started uploading The «file queue could not be emptied since no files have been added message» shows up than upload starts (the backed script gets called normally) but the plugin waits for the server to respond. In Firefox 3, the browser than crashes in Safari 3 the browser sits waiting. Help welcome !
