sorry for the delay, Thus far I've confirmed that a computer authority has not been having problems with
ccleaner n FF1.5.0.2. I've been busy the last few days formatting my hard disk and installing a clean load of WinXP Pro corporate I, I'm installing all of my programs and soon I'll test out ccleaner again.
Update , I now have a clean Windows install and both FF 1.5.0.2 n ccleaner 1.28.277 are working well together. I must have done something wrong in the past to cause the conflict.
