mike_bols you should repair permissions using DiskUtility both before & after installing any softw.

As for ram use, yes, that appears to be a java issue for osx. May I suggest you do certain things to reduce the ram use. Close any windows you don't need open at that time (eg: connections & monitor windows.) LW Prefs>Downlds>Auto-clear completed Dwnlds & tick this option & press the Apply button. Remove old seach results (ie:several hours old.) Hide LW in the Dock when not searching etc. All these things help to reduce/stabilise LW's use of ram.
