And then more details of what is happening. What applications are you using when this happens? What happens? What is the exact error messages.
Also, please state if you are using XP with SP2 or without, and what anti-malware programs you are using, eg which firewall, and wha anti-virus, anti-spyware and anti-adware programs.
I'm running Windows XP Pro with SP2. I get a lot of error messages saying that an application needs to close. I usually click on "Send error report" and carry on working. But that is not possible in the case of "System Restore". When I click on "Send error report" or "Don't send", the application closes and I'm unable to use it. Any ideas please?
