Ever since I upgraded to Google Earth 4, I've had the extremely annoying problem that tilting to an oblique view produced a completely black screen. The only way to get the screen view back was to restart GE. Time to dust off that ol' BSOD acronym...
I just found a thread which provides a clue to why the problem occurs, and gives a workaround (which doesn't 100% remove the annoyance, since it only works for that one session).
Apparently the problem is caused by the use of a dual core AMD Athlon processor. The solution is to set the processor affinity to use only a single core for the GE process. (TaskManager, Processes Tab, rightclick process 'googleearth.exe', 'Set Affinity', select 1 processor only). I haven't yet found a way to persist this setting - anyone have any ideas?
Update: After a few milliseconds more browsing, I found that you can use the imagecfg.exe utility to permanently set the processor affinity for a load image. Running the following command in the Google Earth directory does the trick:
imagecfg -a 0x1 googleearth.exe
