Suddenly, apparently, with LO 7.0.1.2, x64, the memory usage and power usage (when I do ctrl-alt-del) are both excessive, and clearly, they hog my computer resources and bring it to a halt. Often crashes as well. If I have a browser open at the same time, the combined memory usage is, well, all of it. Anybody have any ideas as to what could be causing this?
Please first try with Menu/Help/Restart in Safe Mode, with a clean profile.
how many memory do you have on your machine?
