Please wait while the document is being processed

warning...newbie question....

We are using the crystal report viewer on an ASP.NET application.

on the parameter panel there is an edit icon, if the user double clicks this, the report viewer triggers the page to re-load, then it displays a tiny dialogbox that says "Please wait while the document is being processed" but the report viewer never refreshes. the dialogbox never goes always.

1) why does the edit icon show up on all the parameters?

2) what is it doing when someone double clicks it?

3) how can i hide or disable it?

any help would greatly be appreciated!!!
