OKOK,
wer lesen kann ist klar im Vorteil:
"My application freezes in IntraWeb 7 when I use SendFile, SendStream, or I perform a File-upload?
IntraWeb 7.0 introduces a new feature called LockOnSubmit. This is to prevent the double-click on a form when a submit is still in progress. However, it is incompatible with certain other features. Two of these are the ones above. If you are performing any of these, make sure this property is set to False in the form."
Steht genau so in der FAQ.
Naja, das nächste mal schau ich da zuerst.
danke
