Apple Zen Support Thread

[MeltDown]

I have a minor, occasional glitch in the dropdown menu of this site. It seems to be IE only. Unfortunately it is difficult to capture in a screen shot and difficult to know which search terms to use to resolve it myself. Hopefully my description will ring some bells...
In Categories I have sub-categories. when I first log on, if I mouse over Categories in the dropdown menu, the flyout will at times overlap the Information heading title next to it, creating a jumble of the text of the two upper-most box headings. The issue will resolve itself if I activate any other dropdown menu.

I'm running Zen 1.3.8a on a fresh install and have Apple Zen 2.6 installed.

Thanks!

I've still been unable to resolve this issue. I've tried re-loading key files hoping to kick it into gear but no luck so far. As there may be a conflict that is previously known, I'll list the mods I've added:
