<div class="moz-cite-prefix"> Hi,<br>
<br>
Here is what I have. You can see 4 base layers, and start of
overlays at end. Any of the 3 base layers Google, TMS, WMS
selected will cause overlay TMS to be displayed properly.
Selecting OSM base layer selects tiles with wrong zoom.<br>
<br>
With OSM as base layer it is incorrectly selecting tile such as
this with zoom 10, which is 6 too large<br>

<pre wrap="">How are you creating the TMS layer? Are you using an OSM layer with the
TMS urls? If so that is you problem, TMS and OSM use opposite y dimension
mappings. Use a TMS layer instead.

<pre wrap="">Someone pointed out that I could request tiles from tilecache using TMS
instead of WMS, which I have done and it has mostly fixed my problems.
However, if I use Open Street Map as my base layer then my TMS overlays
are requesting the wrong tiles.
If I don't get any suggestions from the list I am going to file a bug.

from tilecache is only going to work if the tiles are in right project.
Try losing the tileorigin in the constructor as well.
