Hello, I am having a strange problem with ie7 (ie8 in compatibility mode). I have div containers where I am updating values using javascript innhtml to update the values. This works fine in Firefox and ie8. In ie7 the values do not update but if a click on the values and highlight them then they update, also if a change the height of the browser then on the next update the values get updated correctly.
I have figured out that if I change the position property of the outer div container from relative to static then the updates work correctly.
The page can be viewed here http://islendingasogur.net/test/webmap_html_test.html In internet explorer 8 with compatibility turned on you can see that the timestamp in the gray box only gets updated one time, after that you see no changes. The timestamp in the lower right corner gets updated every 10 seconds. But if you highlight the text in the gray box then the updated timestamp values appears!
Here is the page:

The divs with class div_var_value, div_timestamp & div_last_update_time all get updated by the javascript function. The div "div_image_container" is the one that is causing this it seems, atleast if I change the position property for it from relative to static the values get updated correctly
This is the page that updates the values:

I edited the post and added a link to the webpage in question, I have also tested the webpage in internet explorer 7 and this error does not appear there. I have only seen this error in ie8 with compatibility turned on.
If anybody has seen this before and has a fix, I would be very grateful.
Thanks.
