P: Wrong before/after display after changes in crop/straighten (LR 3.4.1)

Normally, the before/after display does not include differences in crop/straighten, i.e. the "before" version always shows the *current* crop/straighten settings (not mentioned in the manual btw).

However, when you go directly from the before/after display (completely zoomed out - "fit") to the crop/straighten tool, change the crop, leave the crop/straighten tool and then directly go back to the same (!) before/after display, the "before" version shows the *old* crop/straighten settings.

Some actions, such es selecting a different before/after view or zooming, will refresh the display so that "before" ist shown correctly in the current crop/straighten settings again.

Windows XP 32 bit SP3.

P.S. This is definitely only a minor bug.

P.S. II. Why does LR beep when using the keyboard shortcut Alt+Y for before/after-top/bottom? Is is because normally Alt-* is used to access the application's menu, but there is no main menu with shortcut 'Y', so is this a windows limitation?

P.S. III. The manual needs to be updated: The shortcut to display *only* the before version is not (no longer?) the backslash, but Shift+S. And the word "before" does not appear in the lower right, but in the upper right of the image.
