I messed with the .ini file and removing the reflections didn't help. It's true no more reflections appeared, but still, only the part of an icon that was on top of the dock was clickable.
I just took it out, saved and then reapplied the dock (changed the background to something else, then back to Aero Reflections. Mine worked fine, moved the icons down and the entire icon is clickable. What do you mean by the bold part?
Btw, I've said it before but I'll say it again. Having reflections on flat zoomer or tabbed docks is stupid.
