Hi, If you have a reason to upgrade to 3.0 do, if you don't and you are happy using 2.6 stay with it. Of course some will post having no issues with 3.0 others have had issues.
I've had it lock up a few times...but too, I have had it be completely stable for days....so not really sure. From what I read, HES is still trying to figure out as to the cause of it the crash.
If you go to flyingpig.com, click the download tab and at the bottom of the list there is a link to the archives page. It will be listed under 2.6. Ryan
