You may be interested in getting the animated effect of the sliding window, if so ignore the rest of this.

If you just want the action to result in opening a window and then collapsing it to show just title bar on MouseOut, you could do a simple mod to any Fetish window to tie the MouseIn and Out to the Collapse button already present on most windows.

Just position the window where the title bar needs to be and the window would be opened by hovering over the titlebar and then leaving the window area would collapse it again.
