I have very similar problem with arrow keys. It looks like some remote keys can be pushed only once. Pushing them for the second, third, etc. time simply does not take any effect. For example I can't navigate my Cambridge Audio CXN V2 menu with ArrowDown and ArrowUp keys. When navigating I can only move one position down or one position up in the menu. Pushing on ArrowDown for the first time works fine, but whenever I push on it more than once it doesn't work..... I feel really frustrated due to that behavior as it makes SofaBaton U2 unusable for me... :( @SupportTeam - is it a known problem ? Will it be fixed soon ? My SofaBaton U2 Firmware is 40, Hardware Version: 4
