[Kst] Antw: Re: Bug

Dear Ben,

Seems like this might be one of the bugs.
With wxMaxima valgrind has really done wonders on bugs that were
reproducible only on one system. Don't know how it does do this. But I
hope that this weekend I will get a chance to try if this is true with
kst, too.

Thanks a lot,
and kind regards,

   Gunter.

Hi Gunter,

I can't reproduce this bug. I used 21 channels with 3.6 million samples
per channel.

I recently reported a similar bug here.

https://bugs.kde.org/show_bug.cgi?id=346547 

I wonder if these two bugs are related? They both involve scalars used
in annotations.

Regards, Ben
