3. the close button in ie tabs wont change if you want to change it to another style of button..
I have reported this to Neil before without it getting fixed. Sks/WB is referencing the wrong image for the close button. You'll find that if you skin the tooltip close button, that image is being used for the IE7 tab close button.
All that is really pointless to me anyway as IE8 tabs and icons aren't getting skinned. Not once has this been addressed by any dev for sks/wb in any thread where this complaint has been brought up. Not even a "shucks....we don't know how to fix it"
EDIT:From this thread Link
IE8 tabs cannot be skinned currently.
Due to how IE8 recolours tabs for different types of site they changed from being a bitmap.
