When displaying gtroff output using gxditview gtroff file | gxditview - pressing the left mouse button in the resulting window displays the usual six-item menu (Next Page, etc), but none of the items can be highlighted or select with the mouse. I'm using all standard 6.0 RPMS. Tried a gxditview executable that works properly on OpenLinux2.2, it fails in the same way as 6.0 gxditview does when run on 6.0 system. I'm unning fvwm2 (not gnome or kde) on 6.0 (kde on OpenLinux). Also tried RH5.2 gxditview on 6.0, broken in same way, but RH5.2 gxditview on RH5.2 system works properly. App-defaults are identical on all systems.
are you referring to /usr/X11R6/bin/xditview? This is the only troff viewer that I we ship with Red Hat, to my knowledge. I just verified that the left mouse button menu works fine here on my workstation with that program. Ah, I bet I know what the problem is. Some Athena-based applications have strange menu behaviour when num lock is on. Make sure numlock is turned off and try again.
