[NTG-context] tilde

Hallo, if I want a non-breaking-space I use a tilde '~' sign. For example in: bakerstreet~13 This has worked in my old context. But now, after my update, I get an very long space. Minimal example: \starttext \framed[align=flushright,width=broad]{Hello~World!} \stoptext Is this a bug? What else kann I use for a non-breaking-space? Wolfgang
