Hey everyone. I'm encountering something I've never really come across before in IE7. I have a wrapper div with a background image applied to it. This image is supposed to repeat all the way until the end of the wrapper div. In IE7 there seems to be a scrolling issue where if I use the scroll bar to see parts of the page that aren't initially visible, the background image will 'cut off' and not repeat in the last 100px or so. This only happens if I have to scroll to see more content. It's like it doesn't fully load the background image for areas that aren't immediately visible.
What's strange is that if I use the mouse wheel to scroll up and down the page, the background image repeats just fine and as it should. If I use the scroll bar though, it will break randomly (never more than 100px but sometimes just the last 20px, 30, 40 etc).
I've tried the following to trouble shoot so far:
1) Added background color to the div as well. The background color breaks as well so it's not just a background image repeating issue.
2) Added a min-height of 1% to the wrapper div.
3) Added a position: relative to the div. I read somewhere that this fixes a weird IE7 background bug. This didn't help.
Thanks for any help. I'm unsure if there's some hiccup somewhere else in my code that is causing this (which I'll continue to look into) or if it's some well known IE7 issue. Again I just find it odd that using the scroll wheel on a mouse let's the background render as it should. Clicking, holding, and using the scroll bar causes it to break.
EDIT: Here is a link to a screenshot of the horrific problem in action. http://skitch.com/flight/dspeh/ie7bgerror The top one is with the error. The bottom screen is how it should load.
Another additional thing I noticed: If I minimize the window while it has the broken background and then maximize it again the background image corrects itself.
