Had been running previous versions of Limewire (e.g. 2.1.x) without problem, but tried installing latest release. After install completed, launched program but instead get error -199. Tried reboot, no effect. Downloaded fresh copy, deleted previous install and reinstalled, no effect. Noticed that min. memory set at 384K and max. mem and preferred mem. sizes set at N/A and boxes greyed out. My guess is that this may be source of problem, but never checked previous versions to see if they are programmed in a similar, non-standard Mac OS fashion.
