invisible dialog box text - OSX 10.6.2 Lyx 1.6.5

[Mark Dransfield]

Hi,

I am a new Lyx user but like it very much. I just upgraded to 1.6.5 but now the
text in the paragraph environment pull-down box disappears when I pull it down
and all the dialog boxes have no visible text except the OK button. Since no-one
else has reported this, I suspect an instal problem may be the cause. Any hints
very welcome.

thanks
Mark
