Sure, but maybe there is a difference between the new files and the recently downloaded files. I don't know.
My confusion is in the fact that the systems that are working are using the newer files as well -- i.e. I installed the 2.60 files on the other systems as well, and the arrows appear normally.
Also, on the system that does NOT show the arrows, I installed the earlier version first -- i.e. the one from the "plugins" section of the JR site. In other words, BOTH the old AND the new versions of the plugin work fine on two systems, but NOT on two other systems. The only difference that I can think of is that on the systems where the arrows DO show up properly, I installed the plugins a while back, whereas on the systems where the arrows do NOT show up, I only installed the plugin recently. The VERSIONS of the plugin that were installed, however, were the same in all cases.
I haven't had a chance to copy the entire folder over yet, so I'll post back when I do this, but I don't think this will help given that I unzipped the SAME plugin files in each case.
The bottom line is that the plugin is not working on two systems.
Thanks again for any help with this,
Larry
