Description:
Hello,

I've been using for MySQL Workbench for 3 months and I must say it is quite a nifty tool, but one thing was bugging me the whole time and still is - occasional UI freezes.

In the previous month I've managed to detect a pattern, when those moments of freezing happen: 
It appears, that if I have "Action Output" selected in the section which is located below SQL editor (see screenshot below):

https://docs.google.com/file/d/0B4LEnyVy9iLtbEMxSWpTSG5oRDA/edit?usp=drivesdk

and execute multiple queries (50-100+) at once the UI freezes for a few seconds.

So importing DUMPS from some other DB is really unbearable experience.

The same thing happens, when I'm trying to import data from .CSV files, that are big enough 5-10MB+.

As the number of queries (or data from .CSV) for that matter increases the longer the UI Freezes (not only does UI become unresponsive, but also it sometimes overlays in a specific shade, that in Ubuntu indicates, that the app probably has frozen.), to a point where you can't tell if you can wait it out or just using System Monitor (or any other Process Manager) just kill MySql Workbench process.

If I just select other type of log instead of "Action Output", then this eliminates, that UI freeze for that moment, but when I open it back, then there is high chance, that UI will freeze again if there is a bunch of new messages.

This is quite annoying.

How to repeat:
- Just run 100+ queries, that execute almost instantaneously i.e. CREATE 100+ TABLES.
- Try to import 10MB+ CSV file into table using UI (without MySql terminal trickery LOAD DATA INFILE 'some_file.csv' INTO TABLE `some_table`)

Please try version 6.2.4. Thanks.

Downloaded. Updated to 6.2.4.12437 build 2426 (64 bits).

Tried creating 137 tables, that freezing UI is still here.

Please try version 6.2.5 and 6.2.3 rc. Thanks.
