Attachment on Oracle forms specifically around .xlsx file extension

 Hi

We've come across an issue with attachments on Oracle forms specifically around .xlsx file extensions, but most likely with all office 2007 'x’ extensions.

Basically it opens the attachment say an .xlsx and considers it as a zip file – you can not open it directly but are forced to save it.

I was wondering if any one come across this issue – maybe there is a workaround?  I.e. I notice in some notes in Metalinks it refers to specifying the mime types for these “x” extensions.  I couldn't find any solution from Metalink but it is a known issue and being investigated.
