Interesting development. here is the code I put in my dectivate:

ZOOM WINDOW "Report Designer" MAX 
MOUSE DBLCLICK AT -0.1,0.1 WINDOW "Print Preview"
IF WEXIST("Page Preview")
	MESSAGEBOX("Exists")
ELSE
	MESSAGEBOX("Doesn't Exist")
ENDIF

I was testing for a window mentioned in the MSDN Librery. I got a messagebox Doesn't Exist but the preview toolbar didnt dock until I closed the messagebox.

ZOOM WINDOW "Report Designer" MAX 
MOUSE DBLCLICK AT -0.1,0.1 WINDOW "Print Preview"
INKEY(.1)
IF WEXIST("Page Preview")
	MESSAGEBOX("Exists")
ELSE
	MESSAGEBOX("Doesn't Exist")
ENDIF

When I added a delay the toolbar failed to dock at all.

I also found another REPORT FORM command version.

   *******
   * This is the report form command that uses the IN WINDOW Clause.
   * Notice that it uses both WINDOW and IN WINDOW clauses. The WINDOW
   * clause tells the Print Preview window to take on the characteristics
   * of the window, while IN WINDOW tells in what window to display the
   * Print Preview window.
   *******
    REPORT FORM report_1 PREVIEW WINDOW printpreview IN WINDOW printpreview

>>>The F3 key (even manually pressed with preview window open) does nothing. I think I am running into the same problem I am experiencing in another thread that I cannot get the horizontal scrollbar to be visible unless I manually click on maximize once the preview comes up (a separate issue). The F10 key does nothing either, only double-clicking in the preview window's title bar or clicking on maximize will actually maximize the form yet the form is the size of a maximized window. As soon as I issue the MOUSE DBLCLICK command in deactivate, the toolbar docks as I want it to but the form is no longer maximized 'literally'. The report designer window never exists - I've trapped for it throughout the entire process. The problem I have is that I send the report to window inside a form using:
>>>
>>>

>>>LOCAL oPreviewForm
>>>oPreviewForm = NEWOBJECT('PreviewForm', 'Pro32.vcx')
>>>REPORT FORM (rpttoview) &prescope FOR &forclause WINDOW PREVIEWFORM PREVIEW
>>>oPreviewForm.Release
>>>

>>>
>>>In the deactivate of the form, I have:
>>>
>>>

>>>*--Preview form class deactivate
>>>DODEFAULT()
>>>IF WEXIST('Report Designer') && <-never runs because it doesn't exist
>>>   MOUSE DBLCLICK AT -0.1,0.1 WINDOW "Report Designer"
>>>   INKEY(.1)
>>>   MOUSE DBLCLICK AT -0.1,0.1 WINDOW "Report Designer"
>>>ENDIF
>>>IF WEXIST('Print Preview')
>>>   MOUSE DBLCLICK AT -0.1,0.1 WINDOW "Print Preview"
>>>ENDIF

>>>>>Thanks for the idea. It starts out at 75% when the toolbar is still hovering over the print preview window and then when the print preview toolbar is docked, it jumps to 100%... I'm looking for any zoom window or any other commands that may be causing that...

However, i would like to get rid of the flash that occurs because the toolbar opens up on top of the preview form and then docks... it also leaves a shadow image of where the toolbar was before it was docked... Anyway to hide it until it is docked?
