Applet runs fine Pre IE 7 Now errors



Hello all,

I'm not a very experience Java programmer. I have much more experience
with C++, but am now trying to figure out some Java problems.

We have an applet that has been working fine for years. Now we have
tried it on IE 7 and get the following errors in the Java Console:

Logging set to : true ... completed.
Trace level set to 5: all ... completed.

We end up with an icon of a page of paper with a red x on it.

I'm stumped. My inexperience here is hanging out like a sore thumb.
Sorry about that. I know what a NULL pointer is (I've had experience
with those puppies). I just don't know where to start with this.
Going by the error messages above, it appears that the problem is in
actual Sun Java code? What's changed in the way IE handles Sun Java
that suddenly breaks this applet?

Any suggestions will be very much appreciated.

Thanks,

Baillie
