Logged on today and found a lock symbol on the Firefox icon. I cannot open the programme unless I do it out of the sandbox. Why is this? My system is Windows XP pro.

Which software are you using to create your sandbox? Perhaps someone is familiar with it, or changes to it.

For some reason my Avast malware killer had put Firefox in its sandbox. Sorted. thanks for the help.
