You not wasting my time. I simple don't know what more to tell you. It could be your graphics card or it could be the engine version. If no one else can answer in 24 hours you might try asking in the "Ask the developers" section, but before you do see if you can find a list of the feature for the Free version to rule that out. Also 'if you can' download the trail version of the full engine and test the code. If the problem still exist with the full engine then you can rule-out engine version as the source. The code is fine George doesn't publish broken code and I wouldn't lie about my test results. So maybe it's a bug or graphics card problem.

I wish you luck and I sorry I didn't have a solution for your problem.
