[Kst] Antw: Re: Bug

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
