As i'm scrolling up and down the man screen there seems to be more flickering than previously. This may be related to the bottom status line "coverage unavailable ..." toggling rapidly with "downloading ...." it's all to fast for me to see exactly whats happening.
Just connected to wifi so that the coverage checking stopped. Now displays just "no downloads in queue" with no switching to another status and the flickering when scrolling has stopped. Seems that PT is checking for coverage and then failing to download too often.
