Slider not working -Boris FX Particle Illusion 2021 Standalone Mac


I have a question about the interface of the software.
For some reason the slider next to the browser window doesn’t work,
I can only go up and down with scroll button.
The other window do have a working slider.
Is this a know issue?


Could you please provide more details. Just which slider is not working and which ones do work? A screenshot would be helpful. Also are you using a tablet or a mouse? There is a known issue where Wacom clicks on scroll bars aren’t recognized so perhaps that is what you are seeing?
