In page http://www.detran.sp.gov.br/, seens that the drop-down list in middle of
page is frozen. I can click in it, use keboard but can't use mouse on it.

This drop-down is into a frame. When I access
http://www.detran.sp.gov.br/clique.html, the drop-down seens just fine.

Reproducible: Always
Steps to Reproduce:
1. Enter http://www.detran.sp.gov.br/
2. Click in the drop-down list (the first option is "- DETRAN SP em um clique"
3. Try to select any option or use the scrollbar

Actual Results:  
The list shows up, but I can't use the scrollbar with mouse (keyboard almost work)

Expected Results:  
Display the drop-down list and allow to use scrollbars with mouse

The selection list (form element) probably doesn't get mousemove events when it
is inside an iframe and the iframe has a defined height (but, removing the
height will destroy page layout). Confirming on branch FF 20040722 and Mozilla
1.7. There are some possibly related bugs (search Bugzilla with keywords "iframe
mouse").
Confirming and changing summary.

Good testcase, but this one is slightly better, because this one is directly
viewable

Good shot, Martijn. How did you managed to get the url for the embedded html
file? IIRC, this was once possible by attaching the files then noticing its url
in bugzilla. This time I could only get a mangled cgi link.

I used a a data uri for the iframe.

The testcase seems to work in:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4a) Gecko/20030401
But it doesn't seem to work in:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4b) Gecko/20030507

Yeah, works for me too with current windows trunk build. Marking WFM.
