hello with this version, when i double-click the icon in tray, the interface popup but immediately self-close.
no problem if i click the Virus Chest menu in tray, interface opens ok but if i click in the interface the first tab "Status", the interface closes itself.
i have the free version with only web, file and email protection.
i have already done a software repair by windows installed programs> change> repair.
OS is Windows 7 x64.
