"There are known memory leaks on the PC version causing crashing" I read the eon forums quite regularly, not sure what these are. I'm having the same issue that Vue is only taking about half the RAM available, I'd like to see this one looked at. But I'm not having memory leak issues that you mention.Perhaps you could explain more, and whether there are tech threads open so eon definitely know about these issues? "Some people are reporting crashing in the Plant Editor as well" I think some of these problems were down to faulty installs of V5i for some people. Missing files caused some of the crashes as the V5i disks don't like all CD/DVD drives for installing. The workaround is to copy all the CD files to a folder on your HD and install from there. Cheers
