Occurs in FF 1.5 RC 2:

Reproducible: Always

Steps to Reproduce:
1. Go to cnn.com and click any of the links to open a video clip (in the green box)
2. Close the popup window while the video is playing
Actual Results:  
Dialog box appears, titled "Illegal Operation in Plug-in":
"Windows Media Player Plug-in Dynamic Link Library

The plug-in performed an illegal operation. You are strongly advised to restart Firefox."

I click Ok, and the popup window reappears for a brief flash. Thereafter, FF acts oddly:
- mouseover highlights do not appear on menu items
- clicking menu items does nothing
- clicking links does nothing (other than move the focus)
- if I close all FF windows, the process remains running; I have to kill it

Expected Results:  
None of the above

Using WMP 9. The npdsplay.dll version is (unsure if that matters).

The only extension installed is Mouse Gestures 1.0.2.

Are there any logs or anything where I can dig up more details on the 'illegal operation' in WMP?

Works for me.
the "illegal operation" means that the plugin crashed
