On my 4KSW41 pro the right click randomly stops working. This carries through any selected port when it happens. The only fix is to power cycle the KVM and the right click returns immediately. On some rare occasions it will just start working on its own.
Disconnecting the mouse itself does not fix the problem and the right click will still not be working when the mouse is physically disconnected and reconnected. This behavior also happens with all mice which are connected.
I have 4 systems connected and the right click fails across all four and returns across all four at the same time.
Is this a bug? Is there perhaps a firmware update for this device?
