very bad js performance in different browsers

[anselmh]

In some browsers the live edit doesn' t work properly due to JS performance I think. text input is delayed up to 2sec (to see it in TinyMCE).
It works not in:

• Win / Mac Opera 11 (very fast JS engine)
• Win / Mac Firefox 3.6
• Win IE (9 not tested)
  but works in: (UPDATE: IS NOT WORKING IN ANY BROWSER CORRECTLY)
• Mac Safari 5
• Mac / Win Chrome (9+10beta)
• Win / Mac Firefox 4beta12

Firebug / Webinspector does only output a unspecified issue for tinyMCE which has been auto-fixed in browser.js

Environments:

• MODX Revo 2.0.8pl trad.
• TinyMCE 4.2.0rc2 (4.1.x has the same issues)
• browsers above
• OS X (10.6.6 / i5,8GB RAM) / Win XP Pro (i5 / 1GB RAM) but in all others too. Tested from several pcs and users.

JS errors in IE:
tiny_mce.js?v=208 line 1 character 128567: 'undefined' is NULL or no object

It doesn't appear in TinyMCE standalone. Any suggestions?
Clients often use IE or Firefox 3.6 where it hass very bad performance… =/

I have the same problems yeah. I've already notified Splittingred

Fixed; was an issue with the forced_root_block setting. Fix is in 4.2.0-pl.

It actually isn't fixed. I've got these performance lacks in every major browser (even google chrome 11).

While writing long texts (as a long blog entry) I recognize performance lacks in typing<->seeingwhatstyped. It isn't synchronized and some times it takes about 5secs to see what are my last 3 words I typed.

Thank you for getting into that.

This issue is still not "closed". It appears in IE and even in Chrome/Opera/FF on older machines.
