JavaScript / Opera Widget: Memory Hole
bei diesem von mir angepassten Opera Widget gibts irgendwo ein Memory-Leak, das ich einfach nicht aufspüre... d.H.: wenn man das Widget am Laufen hat, verbraucht Opera kontinuierlich mehr RAM bis es schließlich bei 100% RAM- und auch CPU-Auslastung angekommen ist.
Bin übers Wochenende in Italien klettern, kann also erst am Montag wieder antworten

<description>
The intent of the 'Infocon' is to reflect changes in malicious traffic and the possibility of disrupted connectivity.
