I don;t understand, what kind of message do you mean?

NOthing, because as long as the rendering is in progress, piave will not 
process any other command. Well, there are three types of commands 
"standard", "drop", and "priority". <seek> is a "drop"-type. all other are 
standard. there is no priority command at the moment. Priority commands would 
even be process ed during rendering (it's a sperate thread).

sure. this commandline option is only for testing. there are three sizes 
involved: 
- full size 
   given by the video source
- render size 
   this is the resolution the effects will be rendered in. While editing it's 
   good enough to have this at full size/2.  For final rendering it must of 
   course be full size.
- display size.
   right now this is by defaul full/2. There should be some dialog box to 
   select 100% 75% 50% 25%   and also I should make the video window honor 
   resize events, so that you can have any display size by just resizeing the  
   window. I think hat shouldnot be too dificult.

Hmm.. I'll have to think about that.... can you maybe start piave with artsdsp 
by default? Would that help?

Yes, zooming with the wheel works. ... maybe you could make it an option or 
make the timeline and the ruler behave different, i.e. scrolling the wheel on 
the ruler zooms and in the timeline seeks?

Cheers,
