as you may be able to see.... the only other extension's toolbar buttons i have are: IE View, Media Player Connectivity, Web Developer.
The issue is when i try to hover over the back or forward buttons, when they are active, ... they seem to cause a shaky effect, which is probably due to unequal back or forward buttons which appear during the hover.
Is there anything that I can do to avoid this? I have stylish enabled, but I do not think I have manipulated anything that relates directly to the images of the toolbar buttons.
