I just tried installing the lyx 1.5 beta debian package (linux) that was mansioned a bit earlier but I couldn't get hebrew to work with it.
Setting default laguage, keyboard and document to hebrew, I still got the input in english letters compiling the document did produce hebrew text though instead of the english letters that appeared on screen. If I changed the X11 input to hebrew I got hebrew letters on screen which came out reversed on screen but ok in output, in english mode they came out ok on screen but the document won't compile (either the text is unrepresentable in the encoding or encoding not available with latex) When I opened hebrew documents created with lyx 1.4 the whole text was reversed (left to right instead of right to left)
