Hello, I have found a bug. When in the following configuration:

• Read Mode OR Fixed-width scrolling
• Viewing two pages at once (i.e. bottom of one page and top of the next page are both visible on screen)
• Using the touchscreen of my 2-in-1 (HP Elitebook G4 if that's relevant) to highlight text

I am able to tap once to select a word on either page, but one one of the two pages, I am not able to alter that selection (i.e. grab the little handles at either end of the selection and expand it to include more text). Instead, it treats the gesture as if I am using the pan tool, and attempts to scroll left/right (and if I drag up/down on the handles the page scrolls without changing the selected text).

Upon some experimentation I found that:

• I have no problems using the touchscreen to select text when viewing a single page (in any view mode). I assume Reader is somehow detecting the "active" page, maybe the one most visible on the screen or something, and treating touchscreen gestures on the two pages differently.
• When I use the trackpad/cursor to select text (in read mode or fixed-width scrolling), there is no problem and I am able to adjust the selection. It's only using the touchscreen.
• If the word I initially select is on the "active" page I am able to drag the selection handle to select text over both pages, but not when the initial selected word is on the "inactive" page.

A relatively uncommon scenario for most users I think, but it's juuust disruptive and irritating enough to prompt me to post about it here (and yes, I'm aware I've spent longer typing this bug report than the cumulative time the bug will take from me! Please fix so that the time can at least be a martyr for all touchscreen users time!) :)
