Ok, well my colleague has that ID and is on a vacation right now.
We will contact You somewhere after next week for this.

thanks, Bart

Apologies for my late reaction.
But, no, I am not using JSAPI yet.
I guess that's what I am looking for.

We obtained a costumized version of jfileupload (namely being able to define a network directory to upload from).

Can we use to the default JSAPI software ?

Hello, I would like to freeze the screen when a user starts the upload, so its forced to wait for
execution of the upload proces.
How can I detect that the application is busy?

thnks Bart
