Probably everyone else but me knows, but any ways I've found that by using the
tb_cold.bmp[2] # cold image (optional) I can have no disabled buttons visible or have another button bmp (tb_cold.bmp) so in-active buttons look the way I desire instead of grayed out.
Example:
(toolbars.cfg)
Back {
ID_NAV_BACK
tool2.bmp[0]
tool1.bmp[0]
tb_cold.bmp[0]
now, if there were only a way to toggle the state of toolbar bitmaps to show the state of macros that toggle javascript, cookies, etc... that would be more useful than buttons, to me.
