Draw into Paint doesnt work in v11

Hello all.
I posted in the photopaint forum but its pretty quiet in there: I think this is valid here too:.....
I have written a script within corelDraw12 object model that prompts the user to save a selection thats in an unnamed file to a network directory via SaveAs"". this works. Then The macro prompts the user to choose whether or not they want to export the file to a jpeg (200dpi x 200dpi) and then to a smaller jpeg for emailing purposes. This works too. Then The macro offers the user a choice to print the larger jpeg file out of Photopaint.(for reasons too long to explain here).It launches photopaint, opens the specified file Then opens the network printer settings dialogue. This works Also but only in v12.
When I put this macro on a machine that uses the version 11 suite. It stops
at this section of this part of the script....
<code>
Set doc1 = PHOTOPAINT.Application.OpenDocument(nfn)'nfn is defined earlier as new file name variable(string)
<code/>
..........and presents me with an error to the effect of "this application has committed an illegal function blah blah blah"
I have made sure to referance the PHOTOPAINT11 type library
but still it doesnt work.
here is the questionable line in context:-
<code>
Dim CPP As PHOTOPAINT.Application
Set CPP = PHOTOPAINT.Application
With CPP
.Application.AppWindow.Activate
Dim doc1 As Variant
Set doc1 = PHOTOPAINT.Application.OpenDocument(nfn)
PHOTOPAINT.ActiveDocument.Activate
With PHOTOPAINT.ActiveDocument.PrintSettings
.SelectPrinter "\\some_named_server\ColorPASS Z5000"
.ShowDialog
end with
<code/>
any ideas why???
Thanx
Andy.
