No, I havn't tried that.... it would take ages though to add the hundreds of delays between macro commands throughout my pcf.

Anyway, the 'simulate it first' trick is definately working.
I downloaded my PCF again without simulating the macros first, and once again the running order was all messed up.
So just to prove to myself that I wasn't going mad, I ran all the macros in the simulator first and it worked properly.

The only problem is that it appears you have to do this this every time you update the remote. So making minor alterations to your confiiguration ends up taking alot longer than it should.... and you have to remember where all your macros are!
