As far as cross-platform languages and the engines which compile/run them, most people here don't enjoy going through the effort of getting them running. Then again, I could be wrong... :) Tony, it's no more effort to get a cross-platform setup running (in general) than it is to get a non-cross platform setup running. On the Mac side of things, the most popular C compiler is already cross-platform, you just have to make the decision (before writing the application) to use the PowerPland application framework, instead of MacApp. If you are already experienced in MacApp, this is a pain, but if you're open to a new framework, then it's a snap. wX is more of a pain. It took me most of a day to get it running on the PC under the Borland C compiler. On the other hand, it just installed and ran on the Linux box. 10 minute job. Go figure.
