I'd like to suggest an addition to your Installation Instructions, based on Bernd's answer to HomeGnome's question on 4 Aug 11.26. I had the same happen to me, but have just found that dialogue before I asked the same question. My guess is that I'm not the only one.
Add a couple of lines to the instructions to explain that existing WUs in your cache will use the old App, the new App is only used for WUs that are downloaded after the new App is installed.
On a 2.4 Ghz Celeron, gone from +/- 58,000 on several 176 credit WUs, to 45,900 on a 175 credit WU.
Starting from an optimised base, that's impressive. I'm impresssed.

Seeing about a 30% reduction
