Hi there....last nite I upgraded my MAME32 to .57 and installed it on the new XP pro, the prog works fine and started my classic games (1942), half way through the first stage the control of my plane went crazy and took on a mind of its own, hmmm how strange!! so I switched off and started again, and yep same problem. Lucky I have a dual boot option, and started it with Win 98...and guess what no problem!! games worked fine!. I thought it may be hardware (ie arrow keys sticking?? but no luck as it worked in 98) Also, while on this topic I saw an option in XP (not sure where) in regards to "sticky keys settings" does anyone know what this is??? Anyway would love to get a second opinion from another person running MAME32 on XP???. CU NRG ! ..
