I should have tried the workaround...

First, I confirmed that the problem did not go away if I used a 
wheelless mouse...it did not. (Science advances by carefully testing and 
discarding hypotheses...)

Then I thought I would try Tk/Tcl 8.5 instead of 8.4.

But first I thought I should un-install the old versions...There are no 
"make uninstall" targets for Tk, Tcl, or BLT, so I just went through 
/usr/local and tried to delete anything that looked related to those 
packages.

Fedora's package manager will install Tk/Tcl 8.5 and BLT 2.4 from the 
Fedora repository, so I tried that. But then Swarm would not configure 
because it could not find Tk/Tcl. (And neither could I, by searching the 
file system.) Apparenly "configure" cannot deal with installed packages??

So then I used the package manager to uninstall Tk/Tcl 8.5 and BLT, and 
installed Tk/Tcl 8.5 from source. Now when I tried to recompile BLT it 
failed because it found conflicting types/previous declarations of 
Tk/Tcl stuff. Apparently I did not get Tk/Tcl uninstalled all the way 
before installing it again from source.

Marcus indicated that BLT 3.0 may now work with Tk/Tcl 8.5. As far as I 
could tell, this version of BLT exists only as their CVS repository. And 
I was too clueless to figure out how to copy their CVS. (Unlike our 
Savannah site, BLT's does not include directions for downloading, and I 
know nothing about CVS.)

So: a) How do I uninstall old versions of Tk/Tcl?? Search my whole file 
system for anything that starts with "tk" or "tcl"?? Is there something 
like a registry that is going to be screwed up even if I do that?

b) How do I get BLT 3.0 off their CVS? 
http://blt.cvs.sourceforge.net/blt/blt/

c) Wouldn't it be cool if Swarm could use the Tk/Tcl and BLT installed 
by Fedora's package manager? (But- they are Tk/Tcl 8.5 and BLT 2.4, 
which apparently do not get along with each other?)

Thanks again very much for any help...
