Hello, After a lot of search, I finally found what was wrong with my document:
When you have ERT inside image float under 1.1.6fix4 (ps view works fine under lyx-1.1.6fix4), this float is badly imported under lyx-1.2.*. When you try view ps under lyx-1.2.1, latex generated 2 errors. I have built an example (in this example, I use psfrag but you have the same result without psfrag). This lyx file has been designed under lyx-1.1.6fix4. You just have to open it under lyx-1.2.1 and do a view ps. Your sincerely, Yann COLLETTE
