My system: Windows7, 64 bit, Dual core processor with 3GB memory, Thunderbird 31 (the previous versions had the same problem). I have a gmail and a yahoo address,and the problem appears with both. When I download an attachment, and I want to open from the Saved files list, it doesn`t appear there, the list is always empty. I have to open the file, always from the windows explorer. I did a search on google, but I can`t find a solution. Thanks
