11) RomRaider chews on the ROM for a VERY long time while the progress bar in the lower left flickers spastically

13) Clicked the blue folder icon to open a second ROM for comparison
14) Selected a second ROM and opened it.
15) RomRaider chews either for just a couple of seconds before stopping or for a very long time (behavior vaires) before displaying "Ready..." beside the progress bar in the lower left
