Thanks Kevin, Sorry for the delay. I have been out for Easter break. In order to better diagnose this problem, a few questions: 1/ For clarification, how do you start the IDV on OS X? (You refer below to the runIDV/runIDV.bat scripts.) 2/ Also, since I am not sure which nightly build you were running, could you possibly confirm this problem with the latest nightly build? (We went through many iterations, and I wonder if you have an old build.) Thanks again, -Julien > I've noticed that the latest IDV builds no longer statically sets the > amount of memory allocated to the JVM in the runIDV/runIDV.bat script.
