Will rendering be fixed?

I just made the mistake of purchasing an upgrade to Media Pro. I'd forgotten, during the trial several months ago, how slowly the app renders images.

Sadly, iView MediaPro has become dangerous to use on my Mac: it can now stall the entire system if pushed to certain levels of magnification. So I bought the upgrade.

Are there ANY plans to fix the slow-rendering bug in Media Pro? It's been quite a while since PhaseOne released its version.

I can't use it like this.
