Be sure not to have anything else open or at least save it prior to trying this
- - make a route, as simple as can be, e.g. : a flange with a bit of pipe on it
- - make a drawing of that route
- - create a BOM of that route (from any view, with or without breaks)
- - edit the BOM (for instance : right click on a row or column so as to be able to hide it)
- - create a break in one of the views
- - edit the BOM again
- Does it crash or doesn't it ?
