Thanks. It didn't occur to me that it would be in Konqueror. I found 
the window where I can change the settings. Took me forever to go 
through it because it listed every file type in the known universe. It 
seems Lyx hijacked everything having anything remotely to do with 
text files. Even script files, etc. Unfortunately, when I tried to 
remove Lyx most of the time Konqueror popped up a window 
saying that the service could not be removed. However, I was able 
to demote it and put another app on top so Lyx will now try to open 
the file only if the top application(s) are not available.

Paul suggested where to look for rogue Lyx references and I'll do 
that later. There may be some others in there too, because I can't 
remove certain other services -- noatun, for example.

That works.

Better solution, except I use only Gnome. However, there is an 
equivalent "Configuration Editor" utility. Under "mouse" the "single-
click" box was checked. I unchecked it, but it didn't make any 
difference. Afer unchecking the box I clicked on Apply, but it still 
tries to open or launch the file with a single click. Then I logged out 
and back in, but still no joy. Finally, I shut down the computer and 
restarted it, but a single-click still tries to open or launch the file. 
And checking in the Configuration Editor, the box is still unchecked.

Must be something else that is controlling it. Logically, it must be 
Konqueror overriding the system settings. But I can't find any 
settings for this in Konqueror.

Wait ... I tried something else. I went back to the configuration 
panel for the mouse and right-clicked on the entry for single-click. 
That brought up a context menu where I could edit the key, unseat 
the key, make it the default, or make it mandatory. Choosing Edit 
popped up a small window, but it was grayed out. Oh well. Didn't 
know what to edit there anyway. Left Unseat alone, as I have no 
idea what unseating does. I chose Mandatory and this popped up a 
warning that I was changing something that the Administrator did 
not give me permission to do. But it also said it might not take 
effect until the application was relaunched. I tried shutting down 
and restarting again, but it did not take effect. I think I have to do 
this as root. But that means I have to launch the configuration 
editor as root or with sudo. I don't know what the executable file for 
the Configuration Editor is. There is probably also a config file 
somewhere that I can edit manually from the command line, if I 
knew what and where it was.

Oddly, single-click has always just selected a file when I am in 
other applications, e.g., OpenOffice.org. It's only in Konqueror 
where it tries to open or launch the file.

Thanks for the help so far. Until I get to the bottom of this at least I 
can hold down Ctrl.
