hi david,
> Send me a page and I'll report.

i have JAWS 5.1, 6.0, 6.2, 7.0 7.1, 8.0 and 9.0 intsalled on my machine

So i asked for an example from you ,where this occurs at it dosn't
tally with my findings, though my test have not been exhaustive.

Are you using a version of JAWS other than those listed? If so which one?
If I know which version then i can test it locally and then make the
test page available to you, to see if there is a discrepency, between
our results.

it would also be helpful to know which mode you are using when it
occurs and which verbosity settings.

regards
steve
