My experience with the "new" DepthCharge software on 
Win2Kpro wasn't pleasant either. (And I posted my complaints 
to this list at the end of January.) During the install there was a 
warning about older components needing to be uninstalled, 
which I ignored, so I shouldn't have expected everything to 
work correctly.

To make a long story short, the new plug-in software worked 
okay in Netscape but not MSIE 5.0 (at all). I soon uninstalled 
the beta and went back to the 1.2 version, which I much 
prefer. Perhaps due to this shuffle, viewing jps files in a 
browser only works with Netscape on my system. I haven't 
figured out how to get MSIE to use the stand alone viewer in 
response to the image/x-jps MIME type. (Instead, MSIE 
complains about not finding an active-x component; rather 
typical brain-dead behavior, with user control needlessly 
obfuscated.)

The old 1.2 viewer supports multiple instances (alt-tab 
switching to different stereoviews), and pressing the tab key 
while looking at a stereoview toggles the display of some useful 
information. The 2.0 beta offers neither of these features and 
has an intrusive "menu" bar at the bottom that doesn't seem to 
add any functionality. (I thought this might allow different 
views to be loaded and then selected for display, but it doesn't.)

I emailed VREX about these issues weeks ago, but never got a 
reply or even an acknowledgement.

A .jps file is basically the same as a .jpg file, but may have 
some extra header information. You should be able to rename 
these extensions either way and view the images in regular 
image viewing software or Depthcharge. I.e. you can take a 
foo.jpg file, rename it foo.jps, and double-clicking will fire up 
the Depthcharge viewer and show it. By convention, the right 
chip image should be in the left half of the .jps image file. If 
you're making .jps files by renaming .jpg files that you create, 
you may want to turn off the progressive jpg feature. I'm not 
sure if progressive jpgs cause trouble with the plug-in or not, 
but better safe than sorry.
