I have Comodo Dragon; Dutch version.
When there was an update beginning December, 2011 I found that the default search engine changed from google.nl into the UK version.
I asked about that on this forum and was helped: "Go To", Options, Basics, Search, Manage Search Engines,
The default was the UK version; I changed the default into google.nl
This week was another update and my default search engine again was changed again into the UK version.
This is not so much a bug; more an annoyance but still. If it can be fixed.......
