I just upgraded to Lightroom 4 and while I am using it, it occasionally turns to a black screen and returns to the program in about 15 sec. I had just upgraded to 6GB of RAM so should have enough of that.
OS Windows 7. I don't have the 4.2 version. I just upgraded to Lightroom 4 this past week. I will download the update to the upgrade if you think this fixes the problem. Also at one point I got an error message that said I don't have enough memory but haven't seen that message again. I have 6GB of RAM and 100GB free on my hard drive. That should be enough, shouldn't it? Thx.
