By the way, some object memory's have a slice object, along with a garbage collector that knows how to deal with them. Lex

On Windows its "-headless". An icon shows up in the system tray. You can click on it and get a live window. Count me as interested. Thanks, -david

The Eye Candy III chang set works fine but when i try resize the window it gets really slow. I don't understand the issues involved to fix anything but maybe it could be fixed. Karl

Re: FreeBSD Squeak Request

Roland Jesse has an updated FreeBSD port skeleton for Squeak 2.7 at http://www.apfel.de/~jesse/squeak/squeak2.tgz. For some reason it hasn't been committed to the FreeBSD ports distribution. It might be wise to delete the current squeak2 port skeleton rm -r /usr/ports/lang/squeak2 Expand the file retrieved above as root with tar -xvzf squeak2.tgz -C /usr/ports/lang Then build squeak like any other FreeBSD port. cd /usr/ports/lang/squeak2 make make install I just did this a week ago. Worked fine. Good luck. 1 3 0 1 3 13013 BOB

The downward slope of the PPS (later PPS/Digtalk, ObjectShare, etc.) stock was virtually continuous from the time of the IPO, with the periodic partial recoveries and eventual greater falls which enriched the market makers coming and going. Check the graphs in the annual statements, 1994-1997. Chris Macie (yet another former employee)

[ENH][Pref] acceptWithPrettyPrint
by Stephan Rudlof 01 Apr '00

01 Apr '00

"Change Set: acceptWithPrettyPrint Date: 1 April 2000 Author: Stephan Rudlof This changeset introduces preference #acceptWithPrettyPrint. If set to true, browsers will automatically format their contents before accepting it (without color). This avoids unformatted sources. Often you type in a method on the fly and leave the formatting to the Browser by setting the preference #acceptWithPrettyPrint to true. But the sources remain ugly. Using this preference is simpler as using the menu methods 'pretty print' or 'pretty print with color'. In addition to the 'pretty print' menu methods formatting works also for new methods.
