Can't drag and drop from or to SmartFTP

I just downloaded and installed SmartFTP to a new computer running Windows 7 on a MacBook pro with Boot Camp.

I am able to download and upload via SmartFTP using the context menu or the filemenu, but not when I try to drag and drop. For instance if I try to upload a file from the desktop, I get the access denied cursor when I move the cursor to SmartFTP.

I use SmartFTP each day at work on a computer with Windows XP, and it works like a dream.

Please post the system information from the menu: Help->About "System Information" dialog.
