It’s been a long time without any new release, but I have not been totally lazy.
While version 2.6.1 of the Animation control only fixes a small regression, the ButtonControls and ComboListBoxControls libraries have been extended by new features. The controls from the ButtonControls library now provide events for extended mouse button clicks. The ComboListBoxControls library controls also provide these new events as well as events for mouse wheel scrolling. Additionally I’ve fixed a bug that did lead to many mouse events being raised with wrong mouse coordinates and I’ve reactivated the data-binding capabilities.

Be aware that the events for the extended mouse buttons depend on the mouse driver configuration. So if they are not raised at all, this is more likely because of the mouse driver than because of potential bugs in the control library.
