There have been a couple times that my screen is blank except the upper and lower toolbars. The screen would have a chapter from the Bible. I need to navigate to another chapter and then I can go back and it is there. I don't remember what I was doing before getting the blank screen. It has only happened a couple times and isn't a big problem. Overall I think version 4 is more stable.

Please let us know if you somehow discover exactly when / how this happens.  Once we can take steps to repeat a problem, we can almost certainly solve it.

I started out with a more complicated routine to get the blank screen, but I got it down to a fairly simple one.

1. Start off with the highlight bar turned off.

2. Turn the highlight bar on.

3. Go to full screen mode.

4. Use lower right hot corner to switch to another version (or even select the version you were in).

5. Scrool down chapter.

6. Exit program.

7. Boot program and you should have the blank screen. You can get the text back either by navigating to another chapter, or it will come back if you x out the highlight bar.

It may not be necessary to scroll down in the chapter in step 5, but it seems to make it more certain to make it work. I am using the NASS with the KJV. I also have the GWHS. The blank screen doesn't seem to appear when switching to the GWHS. It happens when using the hot corner from full screen mode to switch to either the NASS or KJV from any version that I have.

Good work! I have gotten the blank screen probably 8 to 10 times over quite a lot of use, but have not been able to come up with the steps to get it to repeat on demand. I typically got it going from notes or I think bookmarks to "Read," never related to using the highlighter. I got it to repeat following your steps but only if I scrolled down the chapter. Changing the screen from portrait to landscape and back to portrait also causes the text to redisplay. 

It seems I can get the screen by doing any kind of navigation with the highlight bar off, then turn the highlight bar on, exit program, restart program. This navigation can be from bookmarks or probably from links in notes. So it looks like it isn't anything to do with the hot corner.

If you think you get the blank screen in any other way, try going to full screen mode by double tapping the screen and see if the highlight bar isn't active on the bottom line where it was hiding behind the lower toolbar.

Maybe if the hiding toolbar problem is fixed, the blank screen might be also.

Excellent work.  We're working on this now and I'll let you know what we find.

Thanks so much!
