New member here with little to offer but questions I'm afraid. Need to get some input, from the historians here, re:dual core PowerMAC G-5 running OS-X Tiger which has apparently lost two layers from an Illustrator piece I've been working on, on and off, over a very long time. The paths/images are on the screen when file is opened but no longer respond to activation tools. Luckily, I have previously saved version on Flash drive and file works fine, with the two missing layers returned, fully responsive. Is this the beginnings of the end of the G-5, Illustrator program, both, neither? Any, simply stated, input would be most appreciated. Also, does anyone have good ref. for RAM cards from this aging companion and source for GOOD archive quality CD-RW disks? Blow the dust off some of those old articles and throw me a line if you can! Thanks in advance.
