While reading ebooks in Digital Editions my preferred way of scrolling down the page is to hit the down key on my keyboard. However, this only seems to work for about 30 minutes from opening Digital Editions and then pressing the up or down keys does nothing.
I'm rather confused by the problem because it works when I open Digital Editions and if I close it and reopen then I am granted another 30 minutes before it locks up again. Anyone else have this problem or know how to fix it? It's obviously not a huge deal but it's getting a bit annoying.
If it makes a difference I'm running Digital Editions on a Macbook with OS 10.5.5
