Viewing log files

I am trying to configure the plugin system to display ".log" files produced by Apache Tomcat. These are simply text files with a ".log" extension. I have Opus set up with the default configuration for plugins (no added plugins, no changes from the original installation).

When I select a ".log" file the viewer shows a gray pane.

Something is probably "catching" the file type and not allowing it to "fall-through" to the text viewer, but I cannot figure out what. I looked at all of the viewer extensions and none list ".log".

I have not changed the order of the viewers from the installation.

I am running Opus 9.1.1.3.3.3190.x86.

Any ideas?

At the moment Opus won't display files that are open for writing by other programs. That means you cannot view a log file using Opus if it's still being written to by the program that created it.
