Recently we released a number of enhancements to the way blist handles copy and pasting, including improved support for copy/paste of cells, multiple columns, and copy/paste between blist and Excel. To get the benefit of these improvements you need to have Flash 10 installed. To determine which version of flash you have running, visit http://www.macromedia.com/software/flash/about/ — the left most version number (see screenshot) should be a 10 and not a 9. If you are still using Flash 9 or an earlier version, you can download the latest version from the Player Download Center: http://get.adobe.com/flashplayer/.
