Description:
When I use this aplicatiof for cca 1h it becomes very slow. 
When I mark some query and hit "Ctrl+Shift+Return" it needs cca 5s to start executing. When I look in System Monitor, I see that WB uses 200MB+ (when I start it, that value is cca 50MB).

I have 4GB RAM, Intel i5 processor (quad core)

It's very poor to restart application every few hours, since I'm entering queries (not using GUI), so I need to have opened application and its query tabs all  time.

How to repeat:
Use application for a 1h. For example you can export some result set with 1000+ rows and go to "Open SQL script" and execute it. I think that will use more RAM

Please, check if the same problem still happens with a newer version, 5.2.33.

I think it work now normally!
Thank you!

Not repeatable with 5.2.33 it seems.

Workbench Memory Leak

Attachment: Workbench.png (image/png, text), 159.59 KiB.

I have version 5.2.33 and it has a massive memory leak.

Working on a database with around 100 tables, just adding unsigned to all the INT columns and the application choked, pulling a constant 3.14GB of RAM and pronounced CPU spikes on both processors.

Running Window 7 - 64 bit, AMD Turion Ultra Dual Core Mobile M620 2.5GHz, 4GB RAM

See above attachment

I should probably also mention that I was also dragging columns during the process, grouping all my INT, TINYINT, VARCHAR, TEXT etc. columns together for easier reading, so maybe this could be the culprit.

Also, in regard to the attachment.  That memory usage is not going up and down, its just sitting there constantly at 3.14GB while the processors spike as steady as a heartbeat.
