[NTG-context] space in \longrightarrow in lucida (mkiv)

Dear Hans, maybe my request comes a bit late, but nevertheless - how difficult is it to fix \longrightarrow in MKIV in Lucida font? (In MKII it works fine.) \setupbodyfont[lucida] \starttext $\longrightarrow$ \stoptext The arrow has white space in the middle. Thanks a lot, Mojca
