Need help with views in Impress

[Regina Henschel]

Hi all,

if you check "Mouse pointer as pen" in "Slide Show Settings", then the 
graphics, which you paint during running slideshow, are kept when the 
slideshow is stopped and available in edit mode.
The problem is, that they are not visible in the edit window (bug 129898).

Such graphics are assigned to layer "DrawnInSlideshow". It is generated 
during the slideshow. That happens in 
SlideShowImpl::registerUserPaintPolygons. The layer gets the correct 
visibility setting there.

If you create a second view via menu Window > New Window, then the 
paintings are visible. The document has the correct information.

The edit window from where the slideshow starts is remembered with
mpOldActiveWindow = mpViewShell->GetActiveWindow();
in the ctor of SlideshowImpl and restored with
mpViewShell->SetActiveWindow(mpOldActiveWindow);
in method disposing().

How can I get this remembered edit window, which is used after finishing 
the slideshow, to be updated to the changed layer set of the document?

Kind regards
Regina
