I'm not sure about this, but when I use VP 9.02 and open Eula's version of Frontier I get no visible flippers. When I check the Flipper settings under Options > Colors and Formatting > both the Rubber Offset Height and Rubber Width have very strange values which are not equal for both flippers. The RightFlipper has a Rubber Offset Height of, get this, 1144472790
and a Rubber Width of 1138501416 and the LeftFlipper has a Rubber Offset Height of 1040644315 and a Rubber Width of 0 (zero).
Obviously, the vp.exe is doing something very strange here. It is finding no values for these settings because the table is older than the existence of these settings, and then the .exe is asserting these unusual values from within the .exe. The values are out of bounds causing my ATI to ignore the rendering. The flippers are still physically operational. They're only invisible. When I set these values to 0 (zero) or a reasonable integer, the flippers render properly.
The .exe needs to assert a set of default values for settings when none are present in the table script, but the size and irregularity of the values being asserted by the .exe on the Frontier table seems to indicate that there is a memory leak in progress, possibly if there are no default values assigned in the .exe if and when they are absent in the table script.
