I recently started using version 2.4, after getting Accelertation, which seems to be needed for the AP to work properly since 2.3.  Previously I was using 2.2 and had no problems with the autopilot.  

Now I find that heading select doesn't trip off on capturing the localiser.  I have to manually turn it off before the localiser intercept, or I just keep going.

Anyone else have this problem?
