Unreliable recognition of double clicks in Z2

[karrikuh]

I noticed that in Zebra2 2.9.1 Linux, double clicks have to be executed faster than usual in order to be recognized. As a result, I often require multiple attempts which becomes annoying quickly.

Don't have the problem under Windows or other Linux apps (including host application which is REAPER). Didn't check other u-he plugins. Can somebody confirm?
