I have a work-around ( I remapped the button2 on the X-Arcade Control Panel to the letter "B" on the keyboard, then altered the .cfg file in MAME). The Keyboard Alt key still opens the start menu, but I'm not using the keyboard, so it's a workaround (the problem has still not been fixed).
BTW, just to let you know where I'm coming from, I've been in IT for 20+ years, I have an undergraduate & graduate degree in Business/MIS/IT/Computer Science, taught undergraduate and graduate MIS/IT courses for 5 years, programmed for 10+ years and I'm an IT project manager with 100 people reporting to me in a matrix organization. I understand computer work-arounds and alternate ways, I compromise and mitigate problems on a daily basis. I was looking for how to diagnose and resolve the problem.
I want this to be a temporary solution. I don't want to remap every emulator I'm running (currently 5 others with more coming).
To answer a couple questions:
hanelyp: I'm not playing on a keyboard, with the X-Arcade, the keyboard is plugged into the Control Panel and encodes the KB keys (I'm assuming this is how the other CP encoders work too (IPAC??)). I already tried swapping out the keyboard, same issue. what I have not tried yet is by-passing the CP and plugging the KB directly into the PC. (I have to pull out the Arcade from the wall to get to the back of the PC, not an easy task on carpet.) but, I do want to try it to identify the source of the problem.
miles2912: sticky keys was turned off as part of the re-installation of all of the arcade stuff, when I reloaded the new HDD.
I don't know if this is significant, but the right-Alt does the same thing. I suspect that the CP encoder may have somehow become corrupted, but I don't know how to confirm that without plugging the KB directly into the PC.
Again, I apologize if I came across impatient originally. I truelly appreciate the assistance. (I seem to have struck a nerve).
And THANKS again, MPTech
