A while algo, I decided to install Chrome Canary on a HP210 running Win7 Starter Ed. At that time, the current 1P/W was not working with Canary. Then, after a few build for 1P/W, it started to work, that is the module was integrated nicely in Canary.
Now, I installed the latest Canary version and the latest 1P/W version on a new Win7 64 bits machine. This time, the current build (220.127.116.11) and the current Canary build don't go well together : 1P/W won't integrate into Canary. I had to install an older build of 1P/W to have the integration, then I updated 1P/W and the integrated module still works. Why then is the integration removed from the current build ?
