Cecil How are you measuring this? Seems to me you don't have a radio (but you will you pot stirrer!(smile))

We did several alpha releases for those that answered N4HY's call to send their info to [EMAIL PROTECTED] to help find the issue. The final alpha release revealed that all of the people with higher CPU load that started in Preview 14 were back to normal loads again due to fixing some threading issues with the CWX form. We spent numerous hours on this and given the success of the alpha test, moved ahead with the fix to other things. You are the first one that I have heard of that still has a problem with CPU load with recent releases. We cannot fix something we don't know about. Only slightly better are the chances of fixing an issue that is reported if we can't duplicate the issue here. This has nothing to do with caring and everything to do with the nature of debugging. Contrary to your statement below, I would argue that we DO care and tend to handle issues with our beta software at a relative speed of light when compared to many other manufacturers. Now that this has been reported, is anyone else still having higher CPU loads since preview 14 (outside of CW mode with or without CWX)?
