|
|
|
- is faster than Firefox 3.5, the high variability of web-socket-js

|
- performance results in overall performance being lower. Middle mouse

- clicks and keyboard events need some work to work properly under

|
- Opera. Also, Opera does not have support for setting the cursor

- style url to a data URI scheme, so cursor pseudo-encoding is

- disabled.
