This tab on the Light-O-Rama Visualizer's Options dialog controls the defaults and actions associated with virtual bulbs:
•Defaults: New fixtures that are created will use these parameters (as needed). You can always change them on the fixture properties later.
•Don't show a warning if a CCR has an incorrect number of pixels: A CCR must consist of exactly 50 pixels, or it may not be simulated correctly. Checking this box disables the warning if a CCR fixture has other than 50 pixels.
•Don't show a warning if the bulb size is smaller than the recommended minimum: Some bulbs have a recommended minimum size that is greater than one. Checking this box will disable the warning.
