wxWidgets Library (wxGTK port)
Version 3.0.4 (Unicode: wchar_t, debug level: 1),
Runtime version of toolkit used is 3.24.
Compile-time GTK+ version is 3.24.14.The problem is that when you to change the link library sorting order using the up/down buttons, the list is messed up wrt sorting order. What is expected, and what always used to work, is that only the selected library is moved and the order of the other libraries remains unchanged.
I attach the initial screen shot + a simple project to demonstrate it. The next post will include 2 more screen shots
