Bummer! It does sound like a ram issue. The ram is related to Java which for OSX is not very ram user friendly. For the time being, close your Connections window in LW (I've heard that can use up considerable ram) which is found under View Show/Hide. Also, it might also be wise to use Auto-Clear Completed Dwnlds found in your LW Prefs-Downloads. Another thing is to clear any old searches that have been sitting there for several hrs. Which OSX version do you have? Did you install the so-called english version or insternational version LW? Do you other apps whilst using LW? Try the above suggestions & tell me if it makes any difference.
