strikenet | Salut,
Je partage ce que j'ai trouvé pour résoudre l'incompatibilité de IE6 à gérer le "hover" dans les CSS.
Ca marche impec ! A quelque chose prés ça donne la même chose que sous Firefox. 
Code :
- nom du fichier : csshover.htc
- <attach event="ondocumentready" handler="parseStylesheets" />
- <script language="JScript">
- /**
- * PSUEDOS - V1.21.041022 - hover & active
- * ---------------------------------------------
- * Peterned - http://www.xs4all.nl/~peterned/
- * (c) 2004 - Peter Nederlof
- *
- * Credits - Arnoud Berendsen
- * - Martin Reurings
- * for inspiring me and finding really sick bugs
- *
- * howto: body { behavior:url("csshover.htc" ); }
- * ---------------------------------------------
