• HTML page consists of an inline-block followed by a block
• Use jQuery to show/hide the block (I am using slideUp/slideDown)
• After slideDown, the block remains invisible in IE8
• During slideUp, the block becomes briefly visible before it is slid away

Test page attached. Note that this page doesn't work correctly in IE8, but it works correctly:

1. in Chrome and Firefox, or

2. in IE8 compatibility mode, or

3. if you remove the .header { display: inline-block; }

I have marked this "minor" because you can work around by ensuring the block is not preceded by an inline-block.

(The reason the preceding item was an inline-block in my real application is that there are several objects which I wanted to be on the same line, and it was easier to do this by setting them all to inline-block rather than messing around with floats)

-------- version notes ---------

I am using jquery 1.3.2. I have tried jquery-nightly.js but this just gives the following dialog box in IE8:

"Stack overflow at line: 1456"

I've also tried building from git, but it doesn't fetch the sizzle dependency:
