I drag file over launcher icon (running program) after which program raises and I drop the file.
Problem I have here is that although program loads the file, it does not gain focus, so I have to alt-tab to it, to gain focus and use program's actions. This ruins drag&drop purpose for me, as if I have to alt-tab then I could first alt-tab and then drag&drop, instead dragging to launcher, waiting application to raise and dropping the file, and then yet alt-tab.
I guess it's one of those Compiz issues, but maybe someone has a tip which Compiz setting can solve this problem, if possible?
