Version:	6.0.2 beta 1	OS:	Windows (version 8)
Assigned to:		CPU Architecture:	Any

Description:
Just installed 6.0.2 beta 1 in Windows 8 64-bit. When I try to open a connection, workbench becomes unresponsive. SQL editor window appears but does not fully initialize into place - just freezes. Only remedy is to restart - but why? It just happens again.

How to repeat:
Explained above simply.

Suggested fix:
Yes, I do suggest it get's fixed - I have no other valuable suggestion on the matter.

I can confirm that also freezes attempting connections to databases other than localhost. I've reverted to release 5.2.47 for the time being.

Please provide the log files generated by Workbench 6. You can locate them from Help -> Locate Log Files

I could not repeat on Windows 8 64-bits:

Note! Workbench uses server version '(5, 6, 12)' from the server instance profile. Make the entry empty to auto pick version from the server.

Prepared options set for server version '(5, 6, 12)' on 'windows' platform: added - 438, skipped - 117, skipped with no value - 4, deprecated - 1

Attached log file for developers.

Hi, where was the file attached? I can't find it here.

Re-attached log file that went missing yesterday. Apparently it didn't get attached after I indicated "Add File" and then logged in successfully when prompted. Visibility is developers only.

Same Problem o Windows 8 x32
Logs are in my previous post

The same is happening to me when attempting to use the Query Browser in Workbench version 5.2.47 CE. Tried a fresh reinstall, tried Workbench Build 6.0.2.10924, tried upgrading MySQL from version 5.5 to 5.6, no change.

The Query screen loads partially and it freezes with full CPU usage of one core. After about 15 minutes it actually unfreezes and displays the screen. Using anything not in the Management and Instance sections would freeze the workbench again.

I'm using Windows 8 x64 and a local MySQL server.

Please try the following:
- go to Edit -> Preferences -> Appearance
- change the Editor Font value to Lucida Console 12 (or anything different from Bitstream Vera Sans Mono 12)
- restart WB and open a connection

That fixes it - thank you!

Fixed as of MySQL Workbench 6.0.5, and here's the changelog entry:

On Microsoft Windows 8, MySQL Workbench would freeze due to font related
issues. 

A workaround was to change the font using "Edit", "Preferences",
"Appearance" to a font other than "Bitstream Vera Sans Mono 12."

Thank you for the bug report.
