Firstly.....great app. Ok, my problem......... I normally shell my front end using regedit. Since I've upgraded to XP 64 bit, I'm having huge problems with the login in" screen showing very briefly on startup. (I'm running a 15Khz arcade screen). Instant sheller works great, but I can't for the life of me sort out this Login in box showing. I've unticked "change the way users logon/off" Plus ticked enable auto login I can't even maually shell my system (regedit).........so am wondering if it's a 64 bit issue? Please please help......it's driving me nuts!!
