I installed LyX 1.6.2 (debian squeeze) and discover that my custom layout files tuned for LyX 1.5.5 do not work.
LyX 1.6.2 reconfigures with no errors, but theorem-like structures defined in my layouts being applied in LyX text lose all headings and nubering, both in LyX and dvi/pdf windows Many thanks for any advise Andrei
