your solution now works, I've read the log and noticed the warning
'cprotect.sty' wasn't installed so I installed it and your solution works
now,
but (sorry for being so persistent) it's way less intuitive and easy to do,
it's a very specific solution where my problem with the preview
environment is global. (I hope I don't sound ungrateful because I'm really
grateful for your help)
I also don't understand, why your solution works? and why did in 2.3.7 it
all worked perfectly well with no intervention on my part?
but when I read my log file, I can't see such an error, all I see that
could be of significance (take it with a grain of salt as I'm new to this
kind of debugging) if you open the log file I send you now with notepad++
on lines 446-447 I get the message:
"
No file lyxpreviewiPHdvi.aux.
\openout1 = `lyxpreviewiPHdvi.aux'.
"

on lines 530-531 I get the message:
"
Package geometry Warning: The marginal notes overrun the paper.
     Add 47.54726pt and more to the right margin.
"

and on line 597-607 I get:
"

important to mention that the lyx file compiles to PDF with no errors at
all.
