I have installed jbuilder foundation on my ibook g4 (tiger) and there seemed to be no problems with the installation but when I double click the jbuilder icon it appears in the dock, bounces a couple of times and then after a few second dissapears. I have reinstalled a few times but it is the same everytime. Am brand new to apple and was just wondering if anyone else has had this problem with jbuilder or is it just me???
