Outlook panes, Office dialogs & ribbon menus don't display correctly

Outlook panes, profiling dialog boxes and ribbon menus intermittently appear in an unexpected manner such as being transparent, blank or as random sized 'blocks'. This applies to MacroView DMF and MacroView Message
​MacroView DMF v7.5 and later releases make extensive use of Microsoft's Windows Presentation Foundation (WPF) technology in creating elements for the graphic interface. Example of this includes Outlook panes and metadata profiling dialog boxes. In certain scenarios it has impacted upon ribbon items. See below for a visual example of dialog behavior experienced previously when hardware acceleration was enabled with a certain Windows video driver :


To resolve this, you need to disable WPF hardware acceleration. This can be done in the registry by navigating to HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics and setting the "DisableHWAcceleration" DWORD value to 1.



There have reports in a small number of cases that disabling WPF hardware acceleration has resolved unexpected Outlook hang behavior.
