Komodo keeps user preferences, a code intelligence database, and a number of other files in a user data directory. It's location on various platforms is described here:

http://docs.activestate.com/komodo/4.4/trouble.html#appdata_dir

Sometimes files in this directory can become corrupted, causing problems running Komodo. If this problem can't be tracked down to a particular file in the user data directory, there is a nuclear option:

• close Komodo if it's running
• delete, move or rename the user data directory
• restart Komodo

Komodo will generate a fresh user data directory.

If you have preferences or a Toolbox you want to keep, move or rename the directory (e.g. "4.4-corrupt") instead of deleting it. You can then try moving some of the files (e.g. prefs.xml or toolbox.kpf) from the original directory back into the fresh user data directory.

This is possibly because your Company's network uses roaming or remote profiles, so when you are at work your User profile directory ( including Komodo's preferences ) are stored on a remote server. The best way to work around this is to instead store your preferences in a different directory on your machines local drive, outside of your user profile area.

1. create a new environment variable called 'KOMODO_USERDATADIR' and set it to a local path such as 'C:\KomodoPrefs\':

- right-click on My Computer and select Properties
- click on the Advanced tab and hit the Environment button towards the bottom
- below the System Variables list, click on the 'New' button
- for 'Variable name' fill in KOMODO_USERDATADIR, for 'Variable value' fill in your local path.

2. Start Komodo. This will create a new set of preferences in the local directory, and hopefully improve performance.

User preferences are stored in the following directories.

On Windows 2000 / XP:

C:\Documents and Settings\<username>\Application Data\ActiveState\Komodo\3.5

On Linux and Solaris:

/home/<username>/.komodo/3.5

On Mac OS X:

/Users/<username>/Library/Application Support/Komodo

You can back-up this folder, then restore it once you've reinstalled Komodo. The one exception is the host-<hostname> sub-folder, which contains system-specific information such as your the intelligence database.
