PicasaUploader to Facebook Problems

So, this is semi-tested theory that hasn't let me down so far.  I use the PicasaUploader App in Facebook to get my pictures from Picasa to Facebook's Photos with frustrating intermittent success.  Sometimes it would go through the process perfectly and others it would never open the browser to do the last step that confirms the upload.  After playing around a while, it seems that <= 9 pictures is the key.  Try uploading 10 or more and it fails, but 9 or below is fine.  I dunno, it sounds arbitrary and strange, but this has worked so far for me.  I post this here in case someone else is having similar problems maybe they'll find this and confirm it.  YMMV.
