As wxWidgets 3.3.0 will be released next month (due date April 15th), I'm trying to compile C::B (last svn 13640) with wxwidgets 3.3.0. Compilation and link under Windows 24H2 with Msys2/mingW64 is OK. When I open C::B, it's OK too. But when I open a project, I obtain several wxCHECK_MSG (one by opened tab containing source code) coming from src/aui/auibook.cpp at line 2592, in SetPageToolTip : apparently something wrong with page_idx (invalid page index). Recently, there has been many changes in auibook.cpp. May be it needs some adjustments in C::B for wxWidgets 3.3 (no such problems with wxWidgets 3.2.6) !
