Dennis, I also forgot to mention the anoying behaviour we have regarding file uploads.
If I have PF set to use ‘Alternative upload machanism’ everytime I try to upload an asset through the designer it fails with the message ‘Error while uploading’. It also kills your session with PerfectForms so if you’ve not saved anything you loose it. Thus everytime I need to upload an asset I have to change the global setting, upload the file and then remember to change it back. This happens with IE & Firefox
