May be completely unrelated, but the flight simulator worked absolutely fine for me the other day (when Codprawn first posted about it). However, the last two evenings I've tried it, Google Earth loads fine, but the PC crashes when I try to switch to the flight sim. Something about a graphics card error - so I assumed it must be my slightly older PC not being up to the job. However, seemed a bit weird that it worked fine when first tried. Everything else on my PC works as normal.
