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?

Confirmed. Works here with 2011.06.11 16:45 and fails with 2011.10.24 21:26.

What else kann I use for a non-breaking-space?

Use a 'NO-BREAK SPACE' (U+00A0). But the behaviour persists. Maybe a better minimal example: \starttext \framed[align=flushright,width=broad]{Hello~World!} \framed[align=flushright,width=broad]{Hello World!} \stoptext Marco
