Some problems ... Do not take into consideration the elements used, but only the malfunctions of the plugin.
Context VISTA 32bits :
1- editing the compiler "GNU GCC Compiler" => "GNU GCC Compiler mingw32-730"
No problem, even on a workspace.
2- modifications of '#WX' => '#wx28_730' : see the image
If there are multiple lines in the compiler paths or the other paths, only the first one is modified. We must start a search again to recover the others.
After asking to make a backup, a message tells us that the backup failed.
Despite this it is a very powerful tool that I find very useful. Thanks to the designer '@MortenMacFly'
