Drag&Drop doesn't work for some programs in launcher

[Nicholas Shatokhin]

For example, I need to send image file through skype or IM messenger. I take this file by mouse and drag it to launchar for opening minimized window. But all applications icons become gray, only browsers not. And I can't to open this windows and drop file.
