I am facing problem in IE6.x.x. when opening pdf document for modaldialog. Some security warning appears and the PDF not getting open. Can you suggest how to solve this problem. This happens only in some machine. We checked all the browser settings in the PC.Any suggesstions please?

Getting : Security Warning instead of opening PDF. In the warning pop up i can see
file name : my URL[The PDF open URL formed in java side with the report name and pasing parameters]
File type : Un known file type

If i click "open", or "save" or "Cancel" the window is getting closed.

I checked the browser setting also. Everything is fine.

Please note : This happens only in some machine, not every time.The problem only occurs first time for the user and from next time he is not getting this problem again[Rare case]. All documents are getting opened successfully.

Please post me if any body facing this problem and let me know the solutions if any.

Thanks in advance.
