$(submenu).css('display', 'inline') vs $(submenu).show(); ?

After making heavy modifications to the css for the dhtml menu I was seeing some bugs in IE6 display of sub-menus. I traced the problem back to the script setting 'display: inline' on the submenu element, and made this minor change to use show() ,which applies 'display: block', instead. In my case this fixed the IE6 display bugs:

dhtml_menu.js (unpacked)

Line 13: $(submenu).hide();
Line 20: $(submenu).show();

Perhaps this could be an option in a future version? Or was there a particular reason you used the display:inline method?
