I have a Dual 2.3Ghz G5 with 1GB RAM. I do not have TM turned on yet. Ever since I installed Leopard, random applications just crash and close out at random moments. It doesn't seem to have a pattern, sometimes it occurs when there is hard drive activity, other times when there seems to be none. It occurs with all types of applications, from Photoshop to Address Book to Firefox. The application crashes and I get the dialog box telling me the application quit unexpectedly and gives me the option to Ignore, Report, or Relaunch. Am I the only one experiencing this issue? Thanks!!
