Double clicking to open attachments in forum posts is still not working due to a glitch in a recent website software update. Attachments can be opened but you need to right click on the dark grey rectangle attachment icon and select 'open in another tab or window'. The attachment will either open in the new tab/window or download. If it downloads, you can open it as you would with any pdf file. We are still hoping the problem will be solved with the next software update.
