Server-side image map web pages do not work properly on some, not all, MS operating systems.

When the mouse dwells over the image map area of the server-side web page the following occurs: The map coordinates text box appears and flashs at a very high rate; The IE process take more and more memory the longer the dwell time, to a max of about 1.9 giga bytes (I.E. there is a memory leak); The CPU usage spikes during the mouse over dwell period, and remains spiked during the after dwell time catch up period (it seems to use about 100% of 1 cpu, overall cpu load depends on how many CPUs you have); The IE window locks up until the text map coordinates box buffer is cleared (can take up to an hour after moving the mouse away from the image map) (on my computer the ratio is about 1 to 1, meaning for every second of dwell time, it will take a second with the mouse NOT over the diagram for the text buffer to be exhausted. I.E. one minute of dwell time creates two minutes of text messages).

On previous versions of Internet Explorer server-side image maps always worked fine.

This issue has been found on 3 computers so far: Two windows Vista 32 bit and one Windows 7 32 bit. However, it worked fine on a friends windows 7 64 bit computer.

I wrote some web notes with more detail including a link to a screen shot showing memory and CPU usage
I also have an example server-side image map web page.

I have searched and searched and not found anything about this issue anywhere (which is maybe just because I didn't find it)

All computers tested were current with windows updates.

Thank you very much for your reply. The web page you re-directed me to is about web development for Internet Explorer. That is not the problem, the web page is fine and passes the HTML 4.01 strict validator at W3C. Also this same issue occurs on any other server-side web page I have been able to find. As an additional note, unless one actually "clicks" the mouse, there is absolutley no interaction between the client IE9 session and the web server during this issue.

As best as I have been able to determine the problem is with IE9.

Maybe this is not the right place to post this, I don't know. My point is that I took a good deal of time to narrow this issue down and write it up. Sorry, but now that someone at Microsoft has seen this post, that is all I intend to do.

I forgot to actually ask a question in my first post: Question 1: does Microsoft know about this issue? Question 2: when will it be fixed?
