property sheet hangs on a CFormView

Hi,
I have placed a CMyPropertySheet with a page and an edit 
control on that page on a CFormView in an sdi app.
If I select print preview then the app hangs. When I debug 
this I find that the property sheet wndproc is constantly 
recieving the same message WM_GETDLGCODE.
Does anyone have a workaround for this?
I have noticed that _sometimes_ (1/10) it works normally if 
I do other things eg switching focus away from the app 
before issuing the print preview command.
 
regards,

We ran into a similar problem with a program we are moving from VC 2.0 to VC 
4.0.  The solution in our case was to add the WS_EX_CONTROLPARENTstyle to 
the child property sheet.  To do this derive a class from CPropertySheet and 
override OnInitDialog, call the base class and then add the 
WS_EX_CONTROLPARENT style using the following:

ModifyStyleEx( 0, WS_EX_CONTROLPARENT );

Hope this helps.
