The resource file is 160 MB, since it consists of (blurrily) scanned images of parsed verb forms for the whole OT - scrolling in this book made Logos use 900+ MB of space, becoming unresponsive and finally crashing with an out of memory error. I think Logos was in "Preparing Library" stage then. CPU usage ran to 100%

I can't reproduce the crash now (opened the media resource Cities of Paul - another from the top 20 largest resource files - and got it to 1,028 MB RAM use, but stable and responsive), but since zero crashes is the goal, you might look if it can handle such stuff more graciously.
