This problem has perhaps already been dealt with on this forum, but I can't effectively narrow down adequate wording for a search query.
When going from Lightroom to my Silver Efex Pro 2 plug-in for processing a particular photo, when I save back to LR my SEP photo I am then taken out of SEP and must reenter (reboot) it in order to process if I choose the same LR photo differently. This is a real time-consuming nuisance. Does anyone know of some way to keep SEP "open" and not have to be "re-booted" after each separate SEP processing procedure?
