I have found that if I double click a tool in the Library window to open a tool, and maximize it using the icon in the upper right of that window then close it with CMD+w, the library or instant details windows are no longer displayed in my default desktop. Attempting to redisplay them results in a quick flash of the library window on the screen but no library or instant details window. If I repeatedly press (several times) the shortcut key for Instant Details, I can eventually get it to display and then the Library windows to display, but they take up about 90% of the screen when they appear.
If I use the minimize icon in the upper right of the tool window when maximized, it reduces it as it was before being expanded - with the Library and ID window open where they should be - as expected.
