i use firestorm most of all i use singularity or coolvl viewer to import .xml files if needed. cool vl viewer DOES see BOM but you need the latest version of it you need CoolVl Viewer version 1.26.22 is the latest one out, well its the one i have anyway, not sure on the code thingy

I use fs 64 for sl and fs 6.02 for open sim because of the hg I do I rather have 2 type one is 32 bit and the other 64 bit have to admit works great, I still work for the jing jing breedables in sl that's why I use it. I can run 2 open sim regions and an sl region without lag on my system don't try this at home. lol
and yes I'm a girl geek.

firestorm doesn't seem to give issues and singularity has more issues viewing its only good to import items cause firestorm don't have import XML, singularity always has can't find assets.
