APEX

I just got APEX 4.0 installed on a test machine and I am test converting some of my applications (converting from APEX 3.2). I have run into an issue which I was hoping someone can help me with.

I have a form that has 3 items on it:

P15_BULLETIN_ID: a Key value - hidden - (which gets passed in)
P15_BULLETIN_PDF: A display type whose source is:
RETURN '<embed src="'||APEX_UTIL.GET_BLOB_FILE_SRC('P15_BLOB',:P15_BULLETIN_ID,null,'inline')||'" type="application/pdf" width="800" height="600" />';

P15_BLOB: a blob (always a PDF) - hidden:
Source: BULLETIN_PDF

I learned from reading the forum that I no longer include all the other items in the BLOB reference like what was required with 3.2.

However, when the embedded source object displays, it now spawns a new (moveable) window where in 3.2, the PDF item was displayed in-line. Having the new window display separately may cause issues. Is there any way to have this window be embedded like in version 3.2?

The users access this page from a link in an e-mail (there is no navigation).

Thank you in advance for your help.
