Hi johnj First which OS are you using? If your using 9 or ealier I can suggest the following. Go under the "Get Info" file in the operating system and up the ram allocation for the Carrara application. To do this first quit Carrara. Second find the Carrara App. file and click once on it and leave it highlited. Then go to the "Get Info" command you can find it under the "File" command when you are in the Finder (desktop). You will see three options, click on memory and make your adjustments. Give it as much ram as possible while not choking off the OS. I used to run Carrara with 128 megs of ram just fine on a 300mhz G3, but it is always great if you can get more ram. I hope this helps, good luck. memaci
