all Lyx-xforms menus completely black

[Jim Dannemiller]

I feel really stupid. I am using lyx-xforms in Ubuntu Feisty. When I 
went to the dialog boxes that allow me to choose the bibliography file 
or the bibliography style, the text was invisible, so the current file 
or a new file that I choose would be invisible. No good. In an attempt 
to get some visible text, I tried to change the Lyx preferences, colors, 
GUI background and GUI text, but inadvertently set the background to 
black. Now all of the menus everywhere in Lyx are invisible - completely 
black. Lyx-xforms is now unusable. I can use Lyx-qt, but I really like 
Lyx-xforms better. I tried uninstalling and reinstalling Lyx-xforms, but 
the preferences must persist because everything is still black.

Any ideas where these preferences live or how to go about getting a 
working version of Lyx-xforms with menus that I can once again see? 
After I get that, does anyone know whey I would get invisible text in 
the dialog boxes for choosing the bibliography files (the oroiginal 
problem that led to the secondary problem)?

Thanks,
Jim
