That happened to me many times since begin using Ubuntu 10.10 64bit

When I browse some website that contain flash content, `sometimes` when I do some actions on the flash content like:
1- Right Click.
2- Click & Drag.

The whole browser get frozen, and I must kill the process to be able to
use it again.

That happen randomly, sometimes happen, sometimes not !

Reproducible: Sometimes

Steps to Reproduce:
1. Open a web page contains Flash content
2. Try to right click on the flash content, or click & drag
Actual Results:  
The whole browser hangs, and need to kill the process then start it again.

Expected Results:  
It should show me some right-menu, or do the action of clicking & dragging

I've got flash automatically by the new option found at the early steps
of install app. of Ubuntu 10.10, which install third-party apps with the
system install.

It would be helpful to know whether nspluginwrapper is involved here.
"lsof -c plugin-containe | grep flash" might indicate that.

Is there a plugin-container process?
Does "lsof -c plugin-containe" have any output?

After entering "about:plugins" in the urlbar, is "application/x-shockwave-flash" listed there?
If so, what "File" and "Version" are listed?

This might be related to nested event loops.

A workaround could be to uninstall npwrapper.libflashplayer.so and install the x86_64 flash player 10.2 prereleases from Adobe:
