There is something seriously wrong with the search and replace facility in v. 22.214.171.124. Every time I start a search or a S&R, I have to turn “regular expression” back on, or it doesn’t work. If some people like me want it always on, and others want it always off, why not offer a choice? You should also let people choose whether to leave Other Options on or off. As it stands, one has to hit it every time in order to turn regular expressions on.
I am using the latest Writer under AMD 64-bit Linux Mint 17 on a PC.
