Anyone else having this problem?

I think it's been happening since I first got the remote. At first, I figured I just was accidentally pressing "up" or in the middle of up and down - but now it's been almost a year and it still happens sometimes (about 15-20% of the time) and I'm sure I'm not pressing "up."

Could this be a problem with the harmony remote? Perhaps the Yamaha receiver which controls all volume for my system (although it never happened with it's remote)?

Thanks!
