Orca Settings dialog is partially unreadable

[Hermann <steppenwolf2 onlinehome de>]

Hi folks,
what happened to the Orca preferences dialog?
The tab Speech is partially unreadable. All synthesizer settings can't be 
adjusted. Orca doesn't show them, neither braille nor speech. You can see 
them in flat review, but clicking on them doesn't bring them up, so no 
changes can be made. Something went wrong I guess.
A similar problem exists in the key bindings tab. The first point, the Orca 
key, is not reachable.
I think a fix is needed urgently.
I use the latest Orca, about an hour ago.
Regards
Hermann
