I tried using LED flashing in 1.07 and all the 3 lights lit up and blink when there are credits available (Omega Race for example).

They must've fixed it!  Dammit!!  I wasn't going to upgrade to v0.107 because of the new graphics stuff, but now I have to.  :)

So how does the I-PAC tell the LED's when to flash, am i right in think that depending on the game, say TMNT, when u insert a coin the player start button flash, at this point does the I-PAC stop the flow from the 0V side of the LED's causing them to go out and the reapplies it again, so it flashes?? If this is the cause could i not hook the +12v side of my lamps up to my PC PSU and then the 0V side of the lamps to the I-PAC??

It supplies a small 5V current whenever the keyboard LEDs (numlock, capslock, scrolllock) are 'on'.  MAME blinks these keyboard LEDs in some games (not TMNT, mostly older atari games like Centipede, Asteroids, etc) to simulate the lighted volcano button blinking on the actual machines when coins are inserted.  But the IPAC keyboar dLED feature really has nothing to do with MAME -- you can manually toggle the capslock key on and off and the IPAC will still light up the LEDs.  And no, you can't just hook up 12V as you've suggested.  You need the previously mentioned power circuit.
