Official word is not consistent here. The developers are spending most of their time building effective code. Support can be very expensive, so fellow users like ourselves try to help each other out.

Can you be more specific about your problem, like if the error message says exactly the same as Ronka's and which OS version, machine, and LW you are using?

2.9.11 works for many, so we need to track down why it doesn't for you. I'd suspect a memory problem, an extension conflict, or maybe a java version.
