I have been using SW for about 20 years and I still haven't gotten this Toolbox thing worked out.
I tend to try and stay away from it.
My main gripe is that every f.....g part is READ ONLY.
How the hell do you make up components that you can retain on your own hard drive, customise them and reuse from the Toolbox?
Every time we update SW A NEW toolbox is installed - wiping out any changes that we have made.
