Modifying the MacroView settings
                                                
To access the settings, click Tools>Viewer Options. The Image tab in the Options panel opens 
.
MacroView stack loading interval: The default is 3 which means that the view in the MacroView window is refreshed every 3 planes based on the current Z location.
Set the stack loading value to:
- 1 if you need MacroView to display every plane (this may result in slower loading).
 - At least 5 for faster loading.
 
Biolucida caches all downloaded macro images. When you reopen the image, Biolucida will preload any MacroView images downloaded in a previous session.
