Hi Hopefully a quick one This happens in any program - Over the last day or 2 I have been experiencing lockups on all programs while trying to save an image or document. This happens whether I am using Internet Explorer, Windows Live Messenger, or Microsoft Office 2007. It varies between whether its the software I am running or Windows Explorer. I am currently running Windows 7 RC (Build 7100) which was a Clean Install NOT an upgrade I have filled out the system spec page, but if it's not showing: PC: Samsung R60plus Notebook/Laptop CPU: Intel Core 2 Duo 1.83ghz RAM: 2GB DDR (not sure of full spec) HDD: Hitachi HTS542516K9A300 160GB Network: D-Link AR5006 802.11abg Wireless NIC I am also running Kaspersky Internet Security 2010 - fully up to date All Windows Updates are installed as soon as they are released, but has mostly been Windows Defender updates for the last week or more. I hope someone can help with this, as it's getting really annoying now.
