Netscape crashes on Mac !!!

Hi,

We are developing a medium size application in java.
http://www.protomap.cs.huji.ac.il

Everything works fine on every UNIX we tried both netscape 3.0
and 4.0x. On WIN95 and NT4.0 under netscape and IE everything seems to work fine also.

However, we are having serious trouble under MacOS (newer versions)
when using both netscape3.0 and 4.0x.
Since the site is intended to be used by biologists, most of which use MACs we cannot afford it not to work.

The problem is that under various circumstances netscape simply totaly crashes.
However, we succeeded "grabbing" the following error:

 java.lang.OutOfMemoryError
 at sun.awt.macos.MacGraphics.<init>(MacGraphics.java:46)
 at sun.awt.macos.MacImage.getGraphics(MacImage.java:17)
 at image_region.ImageMap.paint(ImageMap.java:107)
 at
sun.awt.macos.InterfaceThread.dispatchInterfaceEvent(InterfaceThread.java:53)
 at java.lang.Thread.run(Thread.java:296)
 java.lang.OutOfMemoryError
 at sun.awt.macos.MacGraphics.<init>(MacGraphics.java:46)
 at sun.awt.macos.MacImage.getGraphics(MacImage.java:17)
 at image_region.ImageMap.paint(ImageMap.java:107)
 at
sun.awt.macos.InterfaceThread.dispatchInterfaceEvent(InterfaceThread.java:53)
 at java.lang.Thread.run(Thread.java:296)

The applet implements a scrolling graph.
We use the following widgets:
buttons, scrollbars, textarea, panels, labels.

We tried to enlarge the recomended and minimal memory usage of the
netscape executable, but nothing seems to help.
We suspect that there is a bug in the implementation of one of the widgets on Mac.

Has anyone encountered such a problem ?

HELP and thanks,
Kreso.

You know with all the hype out of Apple about Java you'd think that they would have made it a priority to ensure that there was a robust Java run-time environment for the Mac.  Unfortunately, there really isn't.  You might want to post this in one of the Mac centric areas to get some pointers.

Does netscape crash everytime you load the applet?
