A few times this past year I've encountered problems with the Google Toolbar popup blocker blocking user-initiated popups. I'm all for suppressing uninitiated popup and popunder windows, but I don't like a toolbar that blocks windows that the user asked - by clicking - to open.

Is it reasonable to assemble a list of Use Cases where the google toolbar blocks a popup?

examples below are in shorthand to briefly describe the method and trigger, the are not valid syntax

I've noticed:

1)
window.open() triggered by body.onload()

2)
<a href="page.htm" target="_blank" onclick="dosomething()">
** fixed by:
<a href="page.htm" target="_blank" onclick="dosomething();window.open('page.htm');return false;">

3)
<a target="_blank"> when <a> is within <iframe> and <iframe> src is on another domain

please contribute your observations, and perhaps we'll reverse-engineer this thing and figure out what we're not allowed to do.

or... is this info already published anywhere?
