question about math commands in LyX1.5

[Brian Kidd]

I am trying out the beta version of 1.5 for a Mac Intel machine and  
it seems that the opt-m g *, where * is a lowercase character,   
command is disabled. this command previously created the greek letter  
that corresponds to the lowercase letter and automatically enters the  
math mode. Is there a reason this command is disabled? Will it be  
enabled once the full version is released?

Thanks,
-Brian
