build ID 2000111604

On Windows 2000 with Pointer Shadow enabled, the Shock the Monkey ad on
Mozillazine makes the pointer flicker.
reporter: whose java runtime environment are you using?

iirc, Sun's JRE doesn't like cursor shadows. You might visit bugparade @ 
sun.com to read about it

Did you try it in Windows 2000 with the pointer shadow enabled? It's a new
setting in win2k that was not in win98.

u guessed it, will try it on win2k and comment.
reopening, using the 2000122904 nightly build on win2k with the pointer shadow 
enabled, the mouse does flicker about every second.

Xiaobin, you have Win2000, right?  Can you accept this and investigate it?

Thanks,

   Is there any update on this webpage because I can not see any applets in the 
www.mozillazine.org?
   Please let me know if I am wrong.

 Hi, Claude:
    Would you like to confirm that the website doesn't have an applet now for 
me?
    If there is no applet in this webpage now, I would like to close this bug.
    Thanks very much!

Any applet with animation will make the pointer flicker.
You can see some http://javaboutique.internet.com, 

for instance the applet on
http://javaboutique.internet.com/StarWarsScroller/
makes the pointer flicker very noticably...


& Confirming
   Although I can see mouse flicking every seconds in 
http://javaboutique.internet.com/StarWarsScroller, I can also see the mouse 
flicking frequently in 
http://www.apple.com/trailers/dreamworks/what_lies_beneath.html. That indicates 
it is not only occurs for java, but also for other animated things like movie. 
I would like to say it is a browser general bug rather a java plugin bug. 
Ususally, the UI should not update the cursor when something changes in the 
browser.

   To my suppurise,when I use to visit 
http://www.apple.com/trailers/dreamworks/what_lies_beneath.html. The mouse 
flickers every seconds. 
   This is what I thought:
   Cursor does not flick for java animated applet in IE because IE has a built 
JVM and the same thing for Netscape 4.6. Netscape 6 pulls out JVM out of the 
browser and make it as a seperate thread to run. So browser needs to talk with 
OJI and OJI talks to plugin and this causes a lot of delay which may cause the 
cursor flick. I would like explain the phenomena of above with the same reson. 
Because IE needs to talk with quicktime plugin and then quicktime player plays 
the movie as a seperate thread which may cause the cursor flick.
  How do you think?

Hi, Claude: 
   Please let me know how do you think about this? If you agree with me, I
