It is impossible to change decimal seperator for Latvian locale to ".". Period symbol is used everywhere, but LibreOffice interprets it as a text. Checking or unchecking "Same as locale setting" box has absolutely no effect. This bug was keeping me and my clients away from Openoffice, and now I see that nothing has changed in 5 years and in Libreoffice as well.
ps. OS locale settings are set to "." of course.
Arturs: which LO version do you use? Last stable one is 4.1.4. There's also 4.2.0 RC1. Could you give a try to 4.1.4 and if it doesn't work to 4.2.0 RC1? Try to rename your LO directory profile (or remove it if you don't have any customization), see https://wiki.documentfoundation.org/UserProfile, before each test.
I tried 4.1.4, and currently using 4.2.0.1. Same thing.
maybe the same issue described with italian locale? see Bug 54042
tommy27: indeed the title are more than similar. *** This bug has been marked as a duplicate of bug 54042 ***
