Thanks for the heads-up, Yorrick, I've been waiting for that one.
I've downloaded and installed it and, for a beta, it's pretty slick and robust.
It opens all the books I've purchased over the years from eReader.com (even back in the days when it was Palmreader.com). Except my dictionary -- I have a 600,000 word 40 MB Merriam-Webster. The error message that pops up is that dictionaries are not supported in this version; never mind, eReader said this on their website and that such support will be available in future versions.
Other .pdb and .prc books I've downloaded from time to time off the 'Net are not in the list of books on the BB, so do not work; there seems no way of accessing them. They work okay with eReader on my Dell Axim but I get an "Error synchronising the book list with the filesystem" pop-up when I start eReader on the BB. They are not visible on the eReader Bookshelf. But it's a work in progress so maybe access to those will come with future versions.
Fonts are as crisp and clear as any on a Pearl may be
and the interface is nice. Looking forward to the update already.
