Windows: Graphics preview doesn't work using Lyxlauncher.exe

[Nick Bell]

Apologies if this has been said before, but I have only ever been able 
to get graphics preview to work if I start LyX by running lyx.exe. If I 
use the default LyXlauncher.exe, I can't preview .eps, .pdf (although 
.png works).

Is this a known issue?
