I have an Omega low profile magic lift (from tradetools) and I love it. The magic lift sometimes doesn't work if there's a bit too much friction between the components but a bit of silicone spray usually sorts it out.
It's possible, but I've made it as difficult as I can while avoiding editing source code. It is possible to make it absolutely mandatory but that means that every time I patch the software I have to make sure the modified code isn't overwritten (which is a pain in the arse).
Ah just been busy with uni and other shit. I still poke my head in every day to make sure the place is still running at the very least. It's not like you really need me here anyway :P
The only time I've been able to get that to happen is when I've tried to upload a new avatar and failed (too big etc). It is a bug, just a poor order of operations, replacing the old file before checking the properties.
