I've found the circumstances in which focus switches without breakpoints.

Earlier today I was debugging a project. I left the browser open at the page I was debugging. Then I started working on another project.

I just refreshed the still open page from the first project and a message appeared in PhpED to say it couldn't find the project and breakpoints might not work. There was a tickbox to not show that message again, which I ticked.

Now every time I refresh that page in the browser or visit any page in that web site, PhpED steals focus (ready to display the message?) but does not display the message.

Opening the original project which the page/site belongs to reverts to PhpED not stealing focus.

So the problem is reproducible if debugging a page which is not for the currently opened project.

@plugnplay Thank you so much!!!

Yes, I see this message some time ago, so, this is a bug because the ide try to show the inactive message!!!!

Well, I re-create the project and bum. Problem solved.

Man, you are my hero!!! Thank you again for your time!!!!

Regard,
