>> software most certainly can cause a computer to crash, both personal-class workstations as well as enterprise-class servers. Yes, when there is a bug in the OS, or there is a bug in drivers used by said application, or, as I mentioned, there are hardware issues. The entire point of having protected-mode and user-mode code is to prevent this from happening. Applications *should* not be able to crash an operating system. That's at least the theory, and as you point out, there are times when theory and practice doesn't agree. So, we can look at the variables here, and try to determine where the probable cause lies. Many users, me included, are l are running this with zero problems on exactly the same OS as the one that is crashing for others The software obviously crashes There are four possible culprits that can be behind the crashing The application it self The operating system Some driver A hardware problem Thousands of users have been using the exact combination of the first two for a few days, many of those thousands of users have been using it extensively. I, for one, imported around 5000 images recently, and worked quite a bit on some of them. No problems. I walked away, the screen-saver engaged etc. No hanging and no crashing. So, even when this serious problem quite clearly affects many users, it's far from all. This seriously decreases the probability that 1 and 2 are culprits. Given that the software crashes basically *all the time* for the users in question, if 1 or 2 was the culprit, the laws of big numbers would make this a problem that wasn't wide-spread, it would be everywhere for *everybody* with the same OS version. Logically this points to 3 or 4 as the culprit, but *triggered* by LR obviously. 3 and 4 are doing fine with other applications. Now, LR is probably not taxing regular HW in a dramatically different way than standard applications, such as Chrome the memory hogger. This again points to some driver, and more than likely, the display driver. Having done a lot of video editing with Premiere and Vegas, I have found one major culprit in when computers start crashing. The culprit is nVidia. Their drivers are *notoriously* unreliable, and upgrading to the latest is usually not a good idea. In Vegas discussion fora, there were regular discussions about which specific version of nVidia drivers were working and with what nVideo card. It was hardly ever the latest version, and it usually varied from card to card. NVIDIA GPUs. Good and bad drivers for VEGAS Adobe is going to find the problem, and they are most likely find it is something they do with the graphics driver. Most likely. They will then stop doing this to the particular driver, and things will go back to being normal. Still, after Adobe fixes it, the driver, not LR was the culprit. Oh, and finally, be careful about throwing experience and company name around. I was developing software for Unix before you got out og High School (assuming you've mostly worked in tech since college and you finished about 21 years ago). Some of those years for IBM too. I have been chasing the bugs that you are talking about, and they were *never* in the application it self, but (barring HW issues) always in some driver etc. For years Oracle was a notorious problem, and they therefore required very specific versions and patch levels of Sun OS (best ever Unix from Sun) and Solaris (YURKH for the first few years, MEH ever since) to run. Once or twice the bug exposed bus in the OS, but that was relatively rare.
