Just create a very long search string (copy and paste "works fine"), search for it, close the dialog and reopen it.
Mmmmh... I think there is simply missing a:
GetSizer()->SetSizeHints(this);
Before the Connect() statement in finddlg.cpp. I cannot compile C::B for the moment, but anybody willing to try or on the way to compile C::B anyways step forwards...
I'm currently working on wx2.9 port of the contrib-plugins.
Off topic:
In linux it's ready and working (except for a crash on exit in keybinder caused by event-handler issues, that can be fixed later).
On windows I need some time to create the wx2.9 project-files and test the rest.
If all is working and does not break wx2.8, I will commit the changes.
