All this applies to the X: http://forum.xda-developers.com/show....php?t=2610531
Posting/text box editing works well enough but now on the X, long press/select text (non editing) & any uploads do not work.
Yet freezing is not happening on the X.
Also the Kii keyboard has no conflicts with Maxthon HD either.
SO: Using Maxthon HD for reading/most posting, having the fabulous horizontal compression with the Quick Access editable/movable fav icons IS so good,
And: Having to use Chrome to upload attachments is not so bad.
