Windows 7 - Copy and Paste Issue

So I've been using Windows 7 more since our clients make use of OCS (Office Communicator), which I must say is a really awesome piece of software. Sadly though Windows seems to have issues with copy and paste. First I thought I was going mad...I mean how can you break something as simple as Copy and Paste? Well I can confirm it has been done! I decided to Google the problem and to my surprise found a large number of people having similar issues. So I decided to download Total Commander and use my really old-school tool to copy my files from the one folder to another. A very sad day for Windows 7, else I must say they've come a long way since Vista.
