In the options menu you can select by clicking on "debug options choice" the different choices of debugging:
Debug info will put all alert messages in the debug.txt file of the program directory and put the process tracing in an other debug.txt file which would be created in the default directory.
The other choices permit putting the used matrixes into files so you can check it in error cases
Beware! Only use it when necessary because it will make the process time much longer
Note: common errors are described in the relative section of this help, here
