1. When the Find dialog is in foreground, pressing F3 performs the search twice, so the selection jumps to the second occurrence instead of the nearest one.
2. EE of versions 11.1.x crashes quite often here. What should I do to help you fix it? Just quote you the crash messages with the addresses? Unfortunately, I failed to find any pattern for reproducability of the crashes, all they occur at an absolutely arbitrary moment, different each time… :-(
My OS here is XP SP3 32-bit, EE 11.1.6.
