Running under 32bit Windows, World Machine can easily run out of memory (or more precisely, out of address space) during high resolution builds. This is a direct limitation of the hardware and OS. There is a workaround that increases the available address space to 3GB and will allow you to build larger worlds. Also note that running under 64bit Windows will allow even the Standard Edition to access 4GB of RAM.
Note that running the x64 Professional Edition under 64bit Windows removes this limitation.
The most common cause of crashes in these views is due to outdated video card drivers. Check with the manufacturer of your video card and update your driver to the latest available and see if this has solved the issue.
You can also try going to Preferences->Video Options and unchecking "Use fastest display method". This will improve compatibility with certain older video cards.
