If you are experiencing long launch time in Flash MX 2004, try deleting all the files and folders in your “temp” folder. For me, this reduces the launch time anywhere from 40+ seconds down to about 8 seconds.
In Windows, the user temp folder is located here:
C:Documents and Settings[USERNAME]Local SettingsTemp
where [USERNAME] is your login user name. “Local Settings” is a hidden directory, you have to enable “Show hidden files and folders” under Tools > Folder Options… > View from any desktop window, or Control Panels > Folder Options > View.
Let me know if this works for you or not…
