I downloaded the 1.17.2 version and it runs ok on my laptop (in multiple mode, too!) but on my main computer it crashes on launch. I get a windows dialogue panel telling me that SecondLife.exe has encountered a serious error and has to close. So I've gone back to using version 1.17.12 in order to avoid the 'crash-on-edit' bug.
