Quote - I knew I forgot something... This code should work for OpenGL or Sreed... At least I hope that it does ;-) import poser if poser.Version()=='8.0': import wx.aui def GetOpenGLCanvas(): l=[] for child in poser.WxAuiManager().GetManagedWindow().Children: GetOpenGLCanvasRec(child, l) return l def GetOpenGLCanvasRec(win, l): for child in win.Children: if child.Name in ['PoserGLCanvas', 'PoserPBCanvas']: l.append(child) else: GetOpenGLCanvasRec(child, l) def GetOutputRes(): s=poser.Scene() if poser.Version()=='8.0' and s.RenderDimAutoscale()==2: for win in GetOpenGLCanvas(): if win.IsShown(): return win.GetSize()
return s.OutputRes()

print GetOutputRes()

Thank you. Using wxPython to ask for windowsizes is a good idea. 
I'll publish a version with this code as an extra paket to see if it works for all.
