This has been confirmed with FCKEditor 2.6.3.

Steps to reproduce:

1. Paste the following text in source view:

(Test Data):

&nbsp; <div class="O" v:shape="_x0000_s1026" style="text-align: center"><span style="font-size: 20pt">E-BizL [%] =&nbsp; <div class="O" v:shape="_x0000_s1026" style="text-align: center"><span style="font-size: 16pt">Shipping units with electronic interchange /&nbsp; <div class="O" v:shape="_x0000_s1026" style="text-align: center"><span style="font-size: 16pt">All shipping units (based on actual arrival date)</span></div> </span></div> </span></div>

2. Switch to usual view
3. put the cursor at the start of the word "units"
4. click left-align. the browser is caught in a loop

Browser name and OS : IE 7.0.5730.11 on Windows XP Professional, SP 2

Confirmed in IE6 and IE7. Ok in other browsers.

This bug may be related to #2679.

After some tests, this is found to be the same bug as #2679. Marking this as a dup.

After applying the patch for #2679 the error still persists.

Now, when only putting the cursor to the start of the word unit it will work with the patch mentioned above. But when selecting the whole text and the trying to left align, the editor will crash again and create a huge number of lines like this:

<div class="O" v:shape="_x0000_s1026">&nbsp;</div>

resolved with 2.6.4 beta
