In the process of assessing minisphere backwards compatibility, I found out that Sphere 1.x is quite misbehaved when certain kinds of errors occur.

If one does this in Sphere 1.5:

Code: (javascript) [Select]

try { LoadImage("nonexistent"); }
catch(e) { }

It produces an uncatchable error and terminates the engine, bypassing the try/catch entirely.  This is not really desirable behavior: I don't think I'll emulate that particular quirk.

Oh man this has messed me up many times. Many resource and other functions do indeed quit without throwing an error. I've wrapped my game in a try catch block to catch anything, but many times it just fails flat.
