I have been racking my brain for months as to why the Dimensions (for 1.5, no legacy)  template refuses to work properly when caching of any sort is turned on (i.e. eaccelerator, joomla cache, jre cache 3.1, etc).  It all seems to be tied to the embedded IEPNGFIX (I even tried 2.02a).

While using the FF source view, I noticed no site URL's were showing in the code (only relative URL's were showing).  So, after looking at the PHP used to grab the site URL in the Dimensions template (<?php echo $this->baseurl; ?> ) I wondered if this was a problem.

For Joomla 1.5 it is.  The proper function to use for this is <?php echo JURI::base(); ?>.  After I did a search/replace, the full site URL's were restored to the Dimnesions template.  I haven't looked at other 1.5 templates but I thought I would share this.

This STILL didn't fix the transparent PNG problem for IE6 when caching is enabled!

As far as the caching, the Dimensions template is the only one I have had trouble with.  From what I can tell, I think the problem is with PNGFIX.htc and how it interacts with cached data but, it's the only one with PNGFIX having that problem.  I tried a Templateplazza and YooTemplate and they seem to work OK.

LOL.. Why isn't Dimesions listed as a PNGFIX template on that article?  :-)   

After messing with this for weeks.. I think it's safe to say that Dimensions isn't cacheable with IE6. This is the only template driving me NUTZ with caching. Since there isn't an equivalent for IE6 like Firebug for Firefox, I can't think of a way to debug this and figure it out.

I have used the latest IEPNGFIX 2.02a, edited the template_ie6.php and hard coded the SRC just in case the embedded PHP wasn't picking up the dirname and nothing works...   

grrrr...  IE6 is a PITA!

never mind.. once the cache auto-refreshed, the PNGFIX fails again...

Unfortunately, same result.  After viewing the template harder in IE6, I had to do more work with the CSS to get UL and LI elements lined up right and I still have more work to do on that.  Here's what it looks like cached.

I think the template (a stunning one at that) is just to complex for IE6 and when you throw caching at it, something gets really fubared (tech term you know.. LOL).

Been down that path with TwinHelix already as well     Same result...    Found that site on google a few nights back.  I even found one that converts .PNGs to flash but that was a pig...
