Cannot open downloaded files from Downloads window

Hey Todd,

Great stuff! Addicted to it. Using 0.9.5

Here's a problem I'm facing:
I cannot double click in Downloads window to open a file I just downloaded. (Tried this in Gmail for Apps)
Also, cannot right click.
Only allowed options are "Show in Finder" in front of the files (works, but ... ) and "Clear" at the bottom

Question:
Is this known/intentional/in-progress/something I can help fixing?
