Is there a way to change this? The pointer can get completely lost at times and turning down all effects should not be necessary. I found a mod for the .gfx files in The Secret World, which uses largely the same infrastructure as AoC, and it can give a larger, coloured mouse pointer in that game.
That mod does not work in the AoC files, though they seem materially the same upon inspection.
It does not seem that it would be earth-shakingly difficult to provide options, or to allow a workaround.
