I'm using Chris Wallace's Gallery child theme for Thematic and noticed a weird bug in Safari.
If the mouse pointer is over the category menu when the page loads then the layout goes a bit haywire. I think the problem is caused by my long descriptions for subcategories: http://www.nativenoise.co.za
I found that changing the following CSS code fixed the problem:
#category-menu ul{
padding: auto
}
I changed auto to 0 and it now works.
The whole page gets thrown out a bit while it's loading but it eventually settles. My server is really slow, so it's a pain to watch the site load weirdly before sorting itself out.
