Thanks for the reply, Mike. Your point on bad markup was well taken-- these examples I'm about to post have passed validation against W3C's markup validator (as 4.01 strict). :)
I've got two example files out there that more closely resemble the page that was giving me issues to begin with: http://myorangepeels.com/blockui/blockuirelative.html and http://myorangepeels.com/blockui/blockuiabsolute.html The only difference between the two is: In blockuirelative.html/.css the style on the div "content-zone" is position:relative. In blockuiabsolute.html/.css the style on the div "content-zone" is position:absolute. Please try the following: In IE6 and with the window maximized, go to http://myorangepeels.com/blockui/blockuirelative.html Click the "Block Page" button at the bottom Scroll up and down the entire page The entire page is blocked In IE6 and with the window maximized, go to http://myorangepeels.com/blockui/blockuiabsolute.html Click the "Block Page" button at the bottom Scroll up and down the entire page Only the very top of the page is blocked-- you can scroll to the very bottom and click the "Take Action" button even though the page thinks it is blocked Is this something that can be fixed for blockUI, something I'm still doing wrong, or just something I have to work around? Thanks again for your help with this, I really appreciate it.
