Iā€™m using version 5.3.0.41. There is a bug in the search menu. After start-up, everything is correct and you can select ā€replace in filesā€™. Open an arbitrary file and close it. After that, the menu item ā€replace in filesā€™ is inactive. Only ā€search in filesā€™ is still active. ā€replace in filesā€™ is only active, if a file is open.
