Here is a link to a new build that fixes the 100% CPU issue: https://www.dropbox.com/s/xk1t5xtbrldc91k/Digital%20Power%20Station_1.0.4_HTTPCaching1.zip
Be sure you have 1.0.4 installed as usual. Replace the “Digital Power Station” application in Applications/Digital Power Station/ with the above version.
1.0.5 will be released soon and it will include this fix. Still waiting on Apple for the kernel stuff though…
