There is something weird happening since the 4.3 KomodoEdit upgrade, on CentOS 5.1 with Gnome interface.
Just to make sure, I deleted everything related to old version, including the .komodo directories for all users (floren and root).
The install went OK. After the init process, I left everything default, except the font size.
Now, if I fire KomodoEdit as root user, I cannot replace in files one word at the time. However, the Replace All works fine. More details:
I opened a window terminal and su - password it for root user. Then, I launched KomodoEdit and opened a .php file in /var/www/html directory. The file is 0644 root:root owned. I can also manually edit the file and save it properly.
The words not replaced are highlighted in green:

Anyone else experienced this issue? If yes, I will report it as a bug.
I tested this and it seems to work fine for me, on MacOS / Intel. That being said there may be a Linux-specific issue here we're not aware of. Can you please log this as a bug:

If you can, please also include any error messages you get. The easiest way to view Komodo errors while running on Linux is simply to start Komodo with the -v option:
komodo -v
This will output verbose start-up information from Komodo, as well as any errors. Start Komodo int his way and then attempt to use the Replace functionality. Do you see any errors?

Will do, Jeff. I will run the verbose mode tonight and post in the bug the error output.
I'm not sure, but the file-encoding of 'Latin-1' may have something to do with this... as a test you could try changing the file's encoding to something like 'utf-8' and see if the replace then works.
I'm seeing the same problem on Mac OS X -- "replace all" in the Find dialog works, but clicking "replace" to replace individual occurrences does not.
I ran "./komodo -v" from /Applications/Komodo IDE.app/Contents/MacOS and saw no related error messages. This is all it displayed initially:

It may be specific to PHP files. I tried an XML file and "replace all" worked. The original poster was using a PHP file as well.

Indeed looks like it only affects files with the php extension. But this is not limited to the Edit version, the full version has this problem too.
