Hi again,
The resolution of formulae was unconnected to this bug. Adding the line
"\preview_scale_factor 1.0" to the MISC SECTION of ~/.lyx/preferences
solved that.
For me, instant preview worked as soon as i installed the dvipng
package. However, I get the same error message that you posted from
Hardy's dvipng:
"dvipng warning: at (0,-1) ignored header \special{! /DvipsToPDF { 72.27
mul Resolution div } def /PDFToDvips { 72.27 div Resolution mul } def

{
userdict /?pdfmark systemdict /exec get put }{ userdict /?pdfmark
systemdict /pop get put userdict /pdfmark systemdict /cleartomark get
put } ifelse }"
I also compiled dvipng 1.10 and 1.11, and I also get the error
"dvipng warning: No GhostScript pngalpha output, cannot render raw
PostScript GPL Ghostscript 8.61: Unrecoverable error, exit code 1"
For me, however, instant preview works with Hardy's dvipng package,
without changing "document > parameters > document class > postcript
driver".
Thanks for your help, Martin
