Yep.
Someone asked a question regarding whether the 0.98 firmware update would allow the Cybook to recognize (in the Library)/open/read PalmDoc (pdb) and/or rtf files. So I moved a couple of them to my Cybook. (I guess I should mention that after a day and a half of not being charged, I was taking the time to give it a quick suck-down of electrons from my PC via the USB cable. It had been sucking electrons for about two hours when I copied two sample files to my Cybook.)
Anyway, I was really engrossed in other, Internet, activity, so once I'd moved the files, I ignored the Cybook for about another hour. Then I remembered what I was supposed to check. So I unplugged it and waited for it to change from the 'Connected' screen to the 'Library' screen. And waited. And waited some more.
Finally, I tried the Reset button. Joy!

It flashed off then the Cybook splash screen appeared! Next came the transitional blank screen. And sat there. And sat there some more. And still sat there. Despair!

The Library screen refused to appear.
So I took the plunge and tried to re-install the 0.98 firmware. Joy!

It re-installed itself! Yep. Up came the Cybook splash screen. Up came the blank transitional screen. . . Despair!

The Library screen refused to show. Now the blankety-blank Cybook won't even turn *OFF*!
There is no joy in Mudville (Citrus Heights, CA) today!
I'm praying and waiting for a response from Bookeen.
This has not been a banner day for the Cybook.
