I spent quite a bit of time with a Waves guy on the phone while he remotely ran through my computer. He debunked the advice I had gotten from two earlier support emails about the placement and/or helpful deletion for some Waveshell files....but reitierated the placement of all other dlls as I indicated in my earlier post.

I was able to create problems and crash Vegas with him on the line by adding Waves plugs into a project with a lot of Izotope plugs in place as real time devices. Other research indicates this is most likely an Izotope conflict created largely by using too much CPU.

Izotope, though responsive, has been a lot slower to get very specific, but the game plan for me seems to be to reinstall the Izo RX2 setup (done) and probably run these plugs off line with Wavelab. Izotope, in one response at least, says that their standalone program to use these plugs only works in 32bit mode, so is likely useless for me with Vegas 11 running at 64bits in Win7.

Will report more as I know more......just realize that the Waves advice to delete that one waveshell dll appears to have been bogus.
