On the above URL, the 'password' field is a java input box applet.

If the browser has just been started, and the JVM has yet to be initialized, then this applet will not start appropriately.

Fix:  "Refresh" the page after the JVM is started.  Then the applet will work.

This occurs in Linux, MacOSX, and Windows (works fine in Internet Explorer).  This has ALWAYS been a problem.  Up until version 1.5 of the JVM, this applet wouldn't even start in all.  But now all OS's  require a "refresh" after JVM start.

Possible solutions: 1) Start JVM when browser starts
                    2) keep hitting refresh.

Again, once the JVM is started the first time, then this page works fine.

Reproducible: Always

Steps to Reproduce:
1. Close Firefox
2. Start Firefox
3. Navigate to the URL:
4. Watch the "Starting Applet" in the status bar
5. Once "Applet Started" appears, then try to set focus to the password box.
6. Doesn't work, so hit "refresh".  Now you can edit the password box.

Actual Results:  
as mentioned in the "steps to reproduce"

Expected Results:  
When navigating to this page, a  refresh  of the browser window should not be necessary.  The applet should start fine even if a JVM start is required.

I certainly hope this is an easy fix!  I've reported it before, but that bug is closed as I thought JVM 1.5 fixed the problem (which might have for Firefox 1.5 ... don't remember). (been going on now for 2 years)

Thanks Guys!

Adam, if this occurs in Linux, MacOSX, and Windows as the reporter describes, it's not a JEP bug (JEP is Mac-only).  Whether it's Core:Plugins or Core:OJI or something else I can't say; only that it's not JEP ;)

Eh, sorry. Somehow I misread this as being Mac-only.

wanted to clarify.  

The URL above is the main page to United Overseas Bank web services.  To get to the applet, click the "Login -> UOB Personal Internet Banking" link to get to the applet:

trying to confirm again (just to ensure that I'm not lying!!) that the problem exists in windows.  Have not replicated this with the latest Patches of both Firefox ( and the JVM on my system. (java 1.6.0_01.b06).

To triple confirm....I just installed a new and download Sun JVM 1.6u2 for my RedHat box....cannot replicate the problem. (Have not tried my SuSE box..but since glib is the same (close enough)....)

Perhaps all we need to do is wait for Apple to update their JVM, then we'll be OK.

Sorry for the confusion!

JEP is gone, and probably so is this issue.
