In general the taskbar activation is not that bad in ros for most apps, but I observed a rather interesting malfunction when using Opera 12.18 from rapps.
Initially its taskbar pane is properly pressed,
but as soon and every time I open the options-dlg, the taskbar pane gets unpressed erroneously.
I double-checked: This bug does not happen on XPSP3 and also not on 2k3sp2
Please notice that the minimize/maximize-alternation via taskbar does only work properly in 2k3sp2 when the options-dlg was closed beforehand
I double-checked, this problem happens with:
0.4.13-RC-46-gbb9997c + explorer-workaround of DougLyons from
0.4.13-RC-46-gbb9997c + patch of blueghost from
0.4.14-dev-1012-g820dbfc master head vanilla
Eventually the ticket is a duplicate of
CORE-16705, but I am not sure about that, that's why I filed individual tickets.
