Problem is very simple, if I launch Lister with F3, it always open in the right of the screen, at maximum.
I've just deletd all entries in wincm.ini in Lister options....
I've tried to delete all wincmd.ini...
If I launch Lister standalone and open every file, it is ok.
I'm using TC 32bit in a 64bit OS because I have some plugins not compatible with 64bit. And I use Windows 7.
Sorry for my bad English, I don't use google!!!

edit: how to add a image from my pc???
