Thanks. Remember this is US, not Canadian! :)
Same behavior in Chrome and Firefox. Didn't try anything else.
Didn't see anything I noticed that was unusual in the console in Chrome.
The only odd thing in the apache error log is a persistent "Subroutine TEX redefined at (eval ####) line ####, chunk 1
If have been going through the various CPAN modules and upgrading once that look interesting. Still no success. 29-30 lines in the editor and then nothing. Even when I try to save to another file name, the original code does not come along...just the 29-30 lines.
After hitting a lot of the CPAN upgrades, the "Subroutine" error no longer appears in the error log when clicking on "Edit" in the browser. The set that got rid of that was
1049 sudo cpan File::Copy
1050 sudo cpan File::Find
1052 sudo cpan File::Find::Rule
1053 sudo cpan File::Path
1054 sudo cpan File::Spec
1056 sudo cpan File::stat
1058 sudo cpan File::Temp
This is now what I get in the apache error log when restarting. Nothing else arrives now when I click on Edit.
