Okay, suddenly it does. Using XAMPP as you recommended it in your latest video, but images not loading sometimes unless I refresh and clearly some sort of delay here with page loads. Neither of which I had with Bitnami WAMP Stack, so back to that and you can close this.

I'm not sure what this would be, we'd need more information, so I'll mark unreproducable for now. Panels aren't rendered in any fundamentally separate/different way, the whole of Composr outputs as a Tempcode blob with blocks, that then streams out.

I can't really attest to what particular Windows LAMP installers are best, Rajesh just used the one he was familiar with for the recent video; I think I'd need to be in front of a system to debug how Apache was performing etc. None should have a bearing on something like Composr's SU feature though.

Well the issues I had, including that custom field being linked to the frontend were with XAMPP. Back on Bitnami WAMP Stack and other than the custom post field and the custom topic field both appearing on the new topic form I have had no bother. Not saying it was XAMPP, but it was something that's been rectified by reinstalling Bitnami WAMP Stack.

Weird :S
