restarts from the beginning.

Flash movie starts from the beginning of the movie

Expected Results:  
Should have continued to play while hidden, and un-hiding displays it at it's
current point in the movie.  It shouldn't go back to the start.

This affects Java applets as well.

Well, just discovered that "bug" with a java applet for uploadign file.

I wonder that there still no solution for almost 4 years now. I can't believe the problem is technical, because Firefox already know how to hide an applet/flash/object without destroying it : for example when you switch tab. What's the difference between hiding with javascript and hiding using a different tab ?

I have division with color picker applet hidden inside.
The division is hidden when it is not used and show applet when mouse over and otherwise on mouse out.

In Internet Explore 7.0 
  * Applet loaded on start up after security warning.
  * Color selection remain after applet hide upon mouse out event
  * Means applet is not reloaded
While in Firefox "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5"
  * Applet not loaded on start up but it gets loaded upon every mouse over
  * Color selection in applet gets reset as well

Following are the java console entries
Upon Mouse Over (Division show up as height increases)
======================================
basic: Added progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@b64435
basic: Applet loaded.
basic: Applet resized and added to parent container
basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 239820 us, pluginInit dt 25630534 us, TotalTime: 25870354 us
basic: Applet initialized
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@b64435
basic: Applet made visible
basic: Starting applet
basic: Applet started
basic: Told clients applet is started

Upon Mouse out(Applet Division shrinks)
======================================
basic: Starting applet teardown
basic: Finished applet teardown

I think applet should not be reload upon mouse over event.

According to me it is still an issue

Yes, still an issue.  See also bug 90628.  It's useful to know that IE7 doesn't destroy the applet when the containing <div> is hidden -- that means applets in general are more likely to be able to cope with having their window unmapped.
