Probably best is doesn't go in the FAQ as Tony suggests, because firstly it is not an adequate fix to the problem, and secondly, the visuals architecture is due for a major overhaul which will solve the problem in a cleaner way.

The main reason for it not being an adequate fix is that the visuals are indexed by number in the file primitives.list, and therefore you need to create a new modified version of primitives.list for every new visuals library you get hold of - MESSY!
