Scayt causing serious problems in Firefox 2

[Wiktor Walc]

SCAYT is enabled by default since 3.3 and this is causing serious issues for users using an old Firefox 2. It is actually almost impossible to type text inside of CKEditor. Confirmed using FF 2.0.20 @ Win 2003.

Issue 1

Steps to reproduce

• Open CKEditor demo: ​http://ckeditor.com/demo
• Press the "New Page" button to clear all contents.
• Click inside of editing area, start typing
• Result: nothing happens... I cannot type anything.

Issue 2

Steps to reproduce

• Open CKEditor demo: ​http://ckeditor.com/demo
• Go to the end of article
• Type "Thiz is a test thiz is a test", whilst typing the cursor is moved at the beginning of the first word catched by Scayt.

In the sample article we do not have any errors, but in real life using a word that is not in dictionary happens quite often and this bug becomes really painful.

Let's disable SCAYT on FF2 for now.

The first issue could be reproduced without SCAYT and is a regression of 3.3.

[Garry Yao]

The patch targets the first issue, the fact is that in FF2, we simply have no 'contenteditable' support there, so the hack for blinking cursor in FF3 should not apply to it.

[Frederico Caldeira Knabben]

Please leave the ticket opened after commit, because we still need to have SCAYT disabled on FF2.
