@jens:
It crashed here, just after I finished writing the last post and clicked back on C::B... :-)
No such crash here.
Did you try to remove the devel and output subdirectory and the pch-files (include/*.gch) manually, to be sure everything is linked correctly.
The windows-hack for the mousewheel seems to break the tooltips. I will see if I find a solution.
For the moment, you can just comment out the part of the hack in cbauinotebook.cpp in cbAuiNotebook::UpdateTabControlsArray() (the lines that disconnect and connect the wxEVT_LEAVE_WINDOW and wxEVT_ENTER_WINDOW events).
I found the cause for the crash (shame on me): the dynamically connected event-handler have the control, that sends the event as this-pointer, not the instance of the class, they are member of. But the compiler does not know this (dynamically) and therefore it does not lead to an error, if we call a member-function directly or use a member-variable as pointer.
It's corrected now, also the issuethat the tooltips are closed immediately aftr they are created.
ToolTip-creation gives the focus to the tooltip, this leads to a mouseleave-evemt of the tabctrl, this leads to a restore of the old focus (or set it to the new selected tab) and this closes the tooltip, because it loses the focus.
Should be fixed in the attached patch.
