My Applet runs SLOWLY!

Hello applet gurus,
I'm trying out my first applet. I've written it so it can also appear as a JFrame GUI application. As an application it displays and runs(a Jdbc connection) just fine.
Tested as an applet in Netscape, however, it runs very slowly. It also shows a white, instead of the proper gray, backround. When I position the cursor at the first JTextField
and type my name, the characters show up about 30 seconds later. When I click on a button I've created to input the textfield values and activate the jdbc connection, the button does not react in any way. I received a Windows NT message complaining of low virtual memory.
I'm using Netscape to test the applet, which is stored on my c:\drive. The applet uses Swing components. I have not compressed the sourcecode into a .jar file.
What's wrong with this applet?
Thanks in advance,
Ben Weaver

Hello Ben,
I would have to say the Windoz giving an indication of low virtual memory is a BAD sign
I'll ask the obvious - did you reboot and have the same problem? Are there a whole lot of other apps running at the same time?
If not it's time to look at your code.
Best regards,
Matt

Thanks, Matt. I went back to the code and found a simple error: I had forgotten to add some of my Swing components using 'getContentPane().add'. Instead I merely used 'add.' The curious thing was that the applet had compiled even with these errors! After I fixed them, the applet worked fine.
