Prim Exposure, showing through

UPDATE: This occurs when certain textures are used on the prims. I will download the various textures and look to see how they are different and what might be causing this issue.

Anyone else experinece prims that appear through others, such as a simple lower wall that is 1 meter wide with the second section sitting on top; the lower prim shows through the top at different angles? No, no alpha textures used.

Example how it should look for a simple column:

Top column 10 M long, 1 M round, lower column 3 M tall, 3 M long and both are centered in each other. (This is happening with walls too, well any intersecting prim)

## <- 10 M ^
## |
## 10 M
MMM <- 3 M |
MMM v

But what is happening:

## Top column can be seen through bottom one.
##
##
M#M
M#M

If I make a column that intersects another prim, the smaller one shows through. Not the shiny effect either.

Drop me a notecard in world to remind me if you have an answer. Thank you.
