Look - there can be no debate that ESRI eff-d up with 2.3. It crashes all the time (five times today). Mostly when I move the GUI but today it also crashed when I was removing a IMG file from the table of contents. I'm going back to 2.2 and sending out a message to everyone I work with (the 2nd biggest user of ESRI products in Scandinavia after ESRI) to roll back to 2.2
Plus the crash files are ginormous. It took over five minutes to send the file through my 1GB network connection.
Chip away at the stone...ESRI is driving people towards QGIS. I hope they realize this.
