PG has routinely denied ctfmon.exe global hooks. I often saw the alert but never felt that ctfmon needed hooks so I continued to deny hooks to this program. Last week, I upgraded Firefox to version 1.5 and since that time, I have encountered intermitent problems with Firefox accessing the internet. The problem is intermitent and does not happen all the time. I can usually correct the problem by closing firefox and restarting it (sometimes 2 or 3 times). This morning, I allowed global hooks for CTFMON.exe and the problem I was having with FF seems to have gone away. I can't see how CTFMON has any effect on Firefox but I'm guessing there must be some connection. Has anyone else encountered this issue.
