Editing problems in post-composition box

:smileysad:I am running Windows 7 SP1 64-bit with all the latest updates installed, including the use of IE11 Version 11.0.4.

 

On the machine where this problem appears, I am using a GeForce GTX 660 OC Video Card with the latest available GeForce Drivers (Version 335.23).   The problem has been consistent through the last 5 Video Driver versions - it's not the Video Drivers themselves.

 

Please note operations mentioned below work completely normally on a Windows XP SP3 Machine running Internet Explorer 8.

 

 

I have been experiencing the following problems for a couple of months now:

 

1. Adding a "Smiley" using the Smiley Icon on the toolbar places the Icon at the beginning of the text - not at the insertion point.  See this post for an example.

 

2. Block-highlight is irrational when highlighting smileys - either the beginning colon for a smiley - or the end colon for a previous smiley is autohighlighted.  It is impossible to properly highlight all of an individual smiley in a block-highlight operation.

This happens with both WXP/IE8 and W7 SP1 64-bit/IE11. 

 

3. Splitting a line intermittently causes text to disappear.  I have to manually re-enter the "disappeared" text - it is not possible to recover in any other manner.  I have had two different experiences of this bug while editing this post - the second one disappeared most of the following paragraph when I split the line to change the sentence below to a "Note".  I suspect this is a buffer-management-problem induced by the higher-security model employed in IE11.

 

Note:  I lost the ":I am running Windows 7 64-" part of the first line of this post - when I put the insertion point at the end of that sentence to split the single paragraph into two paragraphs.  This is really annoying when you lose a much-larger-block-of-text when splitting a more-complex paragraph - as mentioned regarding the above.

 

4. Cursor insertion point intermittently skips to a random spot in the text - when I am moving between the editing screen and its toolbars or tabs.  I suspect Item 3 above and Item 4 are related.

 

 

This all seems to be "Lithium Stuff" - related to the use of IE11 and its higher security provisions.  Please fix.
