Well... right now on my Mac, AliasKeys Helper uses about 4 MB, while Safari uses 64 MB. I'm not sure of what happened on your machine, but AliasKeys is certainly not a resources gobbler.

Note that the virtual memory is, as its name implies, virtual. Any Cocoa application is bound to use around 150-200 MB of virtual memory. This is perfectly normal.

Sorry for the late reply. Afraid I don't visit VT often enough. :) BTW, AliasKeys works fine on Intel Macs, even if it's not yet native. Will be soon.
