No problem. The forums are a good source for help providing you can demonstrate you've done something to help yourself before asking others for it.

You need to make a seperate wall segment to solve this. Painting walls from room segments will cause this to happen. I've attached a segment wall .fps template for you. Use the same method I described before to amend it.
Be aware you need to ensure any walls which require CSG functionality e.g. doors are painted using 'paint walls only' from room segments as FPSC doesn't allow CSG punching on segment walls alone. This must be a bug.
Either CSG punching needs to work for segment walls or painting walls only for room segments should only paint a wall, not a floor aswell.
You can work around the problem your having but yes, it is annoying. Oh and if you can't get Firma to work under Win2k you need to spend $15 and get 'Signs' from www.fpsconline.com.
