I have tried playing with the Lightroom brush tool. However I'm concerned something isn't right with mine, Say I was to to lower exposure in an area, many take the brightness out of a light bulb, that is drawing the eye. I'll set the brush to about -2 stops exposure and click on the light. Nothing happens the program freezes. If I click again it says lightroom is not responding, then 10's of seconds later it comes back to life with the edit in place. To me it seems like it is broken, something isn't working right, am I right in thinking it should be near enough instant when making these edits? Now it shouldn't be my PC, I built it myself, to a very high spec. i7, 16gb 1600mhz DDR3, SSD's, Crossfired Graphics etc.
Any ideas?
