Hi Ton. If you removed ram doubler, would you look at your memory control panel and make sure virtual memory is also on? (Ram Doubler 9 is the equivalent, and turns Apple's virtual memory off). Give that a try first. ATM shouldn't interfere, but does use a lot of memory.

A few other steps you can try:
find the Apple Applet Runner in the MRJ 2.2.6 folder, and give that 70 megs too. (let me know if this works--the Applet Runner is supposed has been recommended in the past, but . . . )

Next, would you take a look at what Apple says about MRJ 2.2.6. It's usually not recommended You can reinstall Java with MRJ 2.2.5 from http://docs.info.apple.com/article.html?artnum=75097
