Sorry---by 'navigate', are you referring to PinballX, or the computer in general? The K120s (all four of them over five years) were fine until the Shift keycaps split the rubber membrane and the split would momentarily catch the cap and hold on just long enough to delay flipper release. Only after my fourth board being used for several extra weeks, due to my not really wanting to go shopping, did the switch actually fail to make contact occasionally; at that point I had had enough. The Corsair's mechanical switches give something substantial to pound down on when multiball gets fierce. 'Business as usual' referred to PinballX starting when the desktop icon is clicked, then going through all of the stuff in the log entries through "Starting", which takes 4 to 4.7 seconds. EDIT: PinballX Version 1.98 added about a minute to that. After that, I guess, comes Table selection, and that requires a keypress (Enter), right? But there's no indication of PBX receiving a keycode.....not even from the Escape key, which otherwise functions consistently when I close VP, FP, early PINemhi (later PeH has Esc remapped to 'E'), and others. I have even retyped the keycodes in Setup, using the listed codes, but afterward, PinballX.ini always shows the correct ones, so the board must be generating what it's supposed to.....
