Hi Robert! Sorry to hear about that... can you elaborate on the steps to reproduce the error? Just starting up, or loading your specific patch? If it is your patch, can you post/attach it here and I'll give it a try.
The Waverazor Module Editor probably doesn't get a lot of testing, as we have seen that only advanced users seem to really appreciate it. It makes me really happy to hear that you are among those making use of it ;)
All the best, - Rob
