Right, so I misunderstood, and read it as classes distributed with ImageFx were newer than those distributed with OS 3.9 - but I now understand that the opposite is the case.
But regardless, these classact/reaction classes are several cans of worms in both technically and legally.
So what version of bevel.image and chooser.gadget? Old ClassAct versions? Came along with ImageFx when acquired from Nova? If so they may very well have license issues, as the ClassAct license specifically says that distribution license is NOT transferrable, and rights are only granted to original company, and new owners must get new license. And current owner is Hyperion, apparently, is Hyperion
