Yeah. I'm just looking for a way to stop it from unexpectedly placing a window on top while I'm working on something else.
For example, Synaptic might be doing its thing in the background while I'm browsing the web, and maybe I open a PDF link on a web page. I carry on browsing the web, and without warning 30 seconds later Okular finishes downloading the PDF and pops up, and 2 seconds later Synaptic steals the focus from Okular. At best this is annoying. At worst it's dangerous because I could be about to click a link in Firefox, when Synaptic pops up and has a "apply changes" button in the same place which I then unwittingly click.
Surely there must be a way to stop this? I can't believe every LXDE user puts up with it...?
