Well, thank you Robby for C-j and you were correct for the preference settings that was carried over to v4. P.S.: Wow! the speed and quality of responses on mailing lists like this one never stop to amaze me compared to typical MS or Java related forums. ;-) <div class="gmail_quote">On Sat, Jul 5, 2008 at 12:37 PM, Robby Findler <<a href="mailto:robby@cs.uchicago.edu">robby@cs.uchicago.edu</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Well, its a known fact of life when dealing with software that is using more than the available memory on the system.
