[Chameleon] Pixel to Geo Conversion problems

I've previously reported that my PrintWidget did not use the updated
extents of my DHTML map (e.g. after a zoom operation). It appears that
my 'stock versions' of Query and ROI widgets are also affected (under
IE5.5).
In the case of Query, I used debug messages to discover the values of
click coords, and its clearly evident that the min/max extent are always
the same. For the ROI widget, defined regions are displayed as though
the map were displayed at full extent. If I zoom in, define an ROI, the
region appears scaled and positioned according to the original extents.

REcenter widget works OK, but it doesn't do a pixeltogeo conversion, so
I'm wondering where to look for the problem.

Anyone experiencing similar problems? suggestions?
To reproduce the problem, try doing a point query at a couple of
different display extents here: atlas.planyukon.ca/chameleon/htdocs
