[e-users] mouse doesn't work with some sliders

[Gabriele P. <daf...@gm...>]

Hi All,
I installed a post production image software, Rawtherapee, which 
generally works but some sliders doesn't.
Normal sliders move left-right but the ones with pyramidal shape doesn't.
I haven't errors in console and I do not what to investigate.

Hany hints??

Cheers
Gabriele
