I have XP proffessional installed, I can open explorer.exe but when I click on anything....it closes down. This only happens if I open it via my computer or using windows key + E or through the start menu. If I open my documents I can use explorer as normal or if opened from the short cut button on my keyboard I'm OK. This never used to happen and its a recent fresh install, I don't know what has changed, but its annoying! Any help would be appreciated.
