Purusant to the above thread which I mistakenly posted in the wrong forum,
If I leave the BattleNet app running for a period, the Play button turns into an Update button. If I click it, I get an error pertaining to the writability of some location in the virtual drive. What do I chmod to get it to function? Unfortunately it doesn't mention the specific location. Will try and get an appropriate error message the next time it happens.
