Clicking on the tray icon causes the annoying habbit of showing the playlist manager window at a different location than at the time of hiding. (Does the window manager chooses the location?) Secondly, the 'playlist button' is always deselected after clicking the tray icon, even when the playlist manager window is still visible.
package gmpc tag 353975 + moreinfo thanks Hello, I am triaging old gmpc bugs and found this 2006 one :) Indeed, this is the responsability of your window manager. It is no different than when you start a new application. What do you mean by "playlist button" ? In the latest version, when I hide gmpc and bring it back, the GTK widgets are still active (I can move with arrow keys for example). Have a nice day and thanks for this bug report.
package gmpc tag 353975 + wontfix thanks Mail to original submitter bounced, so it is unlikely that we'll have a solution for this bug. Closing as wontfix.
