Hello listers ! My problem is fixed now. I installed the build you mentionned and modified the win XP theme to have the active window background in light grey. I selected the win emulation box, and GRETL emulates my personnal modified XP theme, all runs OK. Thanx a lot Allin, it is really a lot more confortable to my eyes ! cheers all sincerely Franck -- Franck Nadaud Economiste CIRED UMR 8568 CNRS - EHESS 45 bis avenue de la Belle Gabrielle 94736 Nogent-sur-Marne Cedex TEL 33-1-43-94-73-94 FAX: 33-1-43-94-73-70 MOB: 06-07-39-92-75 France
