When you use Edit > Find or Edit > Replace, you can represent a line break by typing “\n” and a tab character by typing “\t”. If you want to enter a real backslash, you have to type “\\”.
A single backslash with nothing after it – just “\” – means nothing at all. Previous builds of Cardbox tried to interpret a single backslash as something and would crash as a result. This bug has now been corrected. Cardbox no longer crashes.
Remember: if you want to search for “\”, type “\\”.
