After send MacAppleZoom out and about to many people, I have good and bad news to share. First, the patch to get the left edge of you screen back for one monitor users does work. Second, one can patch it to two monitors, but boy do you get into problems. Both monitors begin to shake, oscillate of beat more likely, and the region that borders the two montors is overlapped. For me, with my main monitor atop my other monitor, I got doubles of inits. There is no way around this. If you hard change the scrn resource of your system and lock it, you cannot get the second mointor to come up at all. If you don't lock this, you cannot avoid the overlap. The author, Horii, feels that the Monitors cdev is at work here, and I concur as a best guess only. I will not post the patch unless you mail me, and I am off for two weeks. I think the screen shake is horrible. It only goes away if you turn the second monitor's power off. Not a great improvement. I have never seen a shake like that except on the RT's monitor down the hall, which an ee thought had a shot power supply or amp or something that sounded expensive... ;-) SO, there is no simple hack to getting two monitors to work short of a hardware hack of the card itself. In addition, the hack requires that both your cards be of the exact same vintage (Apple has released several versions of the color card, and more are on the way according to MacWeek). I tried to get it to go, and I am a semi-crazy hacker. I am not a great programmer, though, so I think it can be done. For those using MacAppleZoom, Horii is quite kind and has verion 1.2 going to paid custormer now. He did not say what it changes or fixes. Please do not email me asking for it. I am (was) able to do so, but after so many people asked ... I must ask that I be allowed to study for exams. If someone could, please post it. As usual, there are lots of opinions and trademarks. Standard discalaimers apply. My school has lots to do with my opinions...but not legally.
