Just bought the NIK filters on Googles big sale - problem is everytime I add a NIK filter - so far only tried Color Efex Pro - via the External Editor in LR4.3, Save, and then go back into LR4.3 the Image Preview keeps reloading while I try to make further adjustments on the image. Impossible to work with as when I use Adjust brush the image disappears for a second as I move the brush around to add my mask.
Interestingly, if I Exit LR4 and relaunch the catalog that same photo with the NIK filter has no problem anymore. The catalog is set to "optimize" everytime I close LR. So why when NIK filters are added can the catalog not work well with them until the optimization process? Do I have a setting wrong in preferences that effects this?
I called NIK (Google) twice. They are useless. A so-called LR NIK expert named "Jessica" is not the expert she presents. She only knows how to have you re-install the software LOL. Then transfers you to oblivion of Google MUSAK. I don't think that NIK LR experts exist there or they are Product Managers who are not on support. Hoping some LR guru might know what is happening with my previews when those filters are applied.
