Memory shouldn't be a problem...i run bryce on a PII 300Mhz comp w/ only 64Mb of ram and only a 4Mb Graphics Accelerator..and it runs fine (well as fine as can be expected) i suggest u start up the program and before u do the task that makes it crash go to the End Task menu (Alt + Ctrl + Del) and one by one end the programs that u don't need...then try the task and hopefully u should isolate the problem (i'm assuming that its crashing due to a program working in the background that is clashing with it)
