For a project, I select "Attach new host by default" and "Attach all hosts now", then click on the Update button

all my hosts are attached to the project but "Attach new host by default" is not done.

Tested this (and am using this myself since forever) and works fine for me.

Anybody else with the problem?

Might be a dumb question, but did you connect the new host to BoincStats BAM! via BOINC Manager Tools menu?

Yes

I just made another try and it don't works.

I'm not attached for the moment at proteins.
I have selected "Attach new host by default" and "Attach all hosts now", then click on the Update button.
My computers are attaching to proteins but the "attach new host by defaut" option is still not selected For this project

Any ideas ?

You were trying to set a project to default attach that has a resource share of 0. That doesn't make much sense, but it's allowed now.

Because I'm not clear with my english (sorry I'm french ;-)) i will try to descibe it with images.
I tried with Proteins just for the test and for me it doesn't work

Step1 : No computer attached to Proteins


Step 2 : I want to attach all my computers and all my future hosts to Proteins


Step3 : I press the Update button

Step4: All my computers are attaching to Proteins BUT the "Attach new host by default" button is not selected
