I am using Liferea v 1.10.5 on Ubuntu 12.04. The problem I am facing is that after waking from sleep mode, Liferea does not accept certain keyboard inputs. I can't move through the lists using the Up/Down arrow keys, or press Enter to open a feed in browser. It is also not possible to change the focus using the Tab key. Although, some keyboard shortcuts do seem to work since I can toggle read status using Ctrl+M or go to next unread item using Ctrl+N. But that is not always preferable.
Any help will be appreciated. Thank you.
