I am using the Flash Builder 4 on a Macbook Pro 2.4Ghz (pretty fast machine) and I noticed that the code editor has gotten extremely slow when editing MXML files. Slow as in 1-character-per-second slow. It's irritating and unusable.
Slowness increases with the number of components in the MXML file. Even files with just a few components show a noticeable lag while typing. Anybody else is experiencing this behavior? I tried disabling everything I could in the prefs to no avail. What can I do to improve responsiveness?
