Same. I have this problem (currently using the release before the december one (too many on my comp. can't discern which im using).
It's not an interference issue, as the remote speed is perfect in Evolution-X. I'm not sure how I should configure the sensitivity, or even if that's what I'm meant to configure (it's not that it's unresponsive, it's just it responds too slowly). 0.4 is too slow and 0.1 is still slightly too slow but is way too responsive (i press a button as normal and usually it repeats that command multiple times. I have to quickly tap the button for it to react once.)
Any other part that I should config? I can live with it, don't get me wrong. I just don't really want to (and since others apparently can get it right, why not me???)
Given I WAS using old batteries (damn remote not coming with any :@) but as soon as I get a new pair I'll post.
Hope someone knows what's wrong though (if it's not the batteries).
Thanks
