After selecting the wrong application to open a particular file, you will need to delete Macintosh Easy Open's preference file, or the wrong application will remain attached to that file. To delete the preference file, open the Macintosh Easy Open control panel, and click the Delete Preferences button.
After deleting the preference file, you will need to rebuild your desktop file this way:
Step 1
------
Restart your Macintosh and hold down the Space Bar until the Extensions Manager control panel opens.
Step 2
------
Use the pull down menu in the Extensions Manager to choose "All Off"
Step 3
------
Scroll down to the Control Panels section of the Extensions Manager window and click the Macintosh Easy Open item to put a check mark by it.
Step 4
------
Close the Extensions Manager window by clicking on the close box in the upper left corner.
Step 5
------
Immediately hold down the Command (Apple) and Option keys until you see the dialog box, "Are you sure you want to rebuild the desktop file?" Click Okay.
Once you have determined everything is working normally, you can go back to the Extensions Manager and turn on all the extensions you usually use. You need to restart to have the reactivated extensions load.
