Hi, I've just started using Maya again, it's been a while and i'm now using 2012.

I've setup a Subdiv proxy, and when i use the split poly tool the subdiv proxy won't update, i used to get round this problem in maya 7 by deleting the history of my low poly mesh i'm working on, and the subdiv would update, but not anymore?

It doesn't matter if i use the old splitpoly tool or the new Interactive split tool, it just won't update?

Any ideas what i'm doing wrong?
