Just spent an hour trying to get window markers to display?

[Anonymous]

Don't know what I'm doing wrong, but all I want to do is to get my windows to display a simple symbol with a number or letter in it in plan view. After an hour of trying No luck at all.
I have tried each option (Basic window-door skylight marker, Builder dimension 17, W marker 17, Window marker_NCS 17 and WTH is load other window marker, why would I want to do that when none of the first options work anyway) along with the settings in the dialog box.

Is this really this complex? First time trying to do this. I can't even get a marker to appear in plan next to a window.

Thanks

Don't forget to check the renovation status as it affects wheather IDs are shown -- just found this out on a current project.
