Hello I found one feature of FEMM I don't like. When I have long filename and I double click on the file in Explorer or WinCommander (I have association of *.fem to FEMM) the filename is converted to DOS format (XXXXXX~1.fem). If the model is opened directly from FEMM everything seems to be OK. Is here any way how to get rid of this feature? Thank you Jiri Vecerka
