Description:
MySQL 5.1.56 (MyISAM table type)

Workbench has encountered a problem.
Index was outside the bounds of the array.

How to repeat:

Typed in and executed: use <db_name>; in "Query 1" tab
Opened new "Query 2" tab with "Create new Scratch Area" button.
Typed in and executed: select max(id) from <table1>;
Query returned a value in "Query 2 Result" tab.
Clicked back to Query 1 tab.
Removed previous text from "use" command.
Typed in: select max(id) from <table2>;
...
Workbench has encountered a problem.
Index was outside the bounds of the array.

The correct result gets returned when I click the close button on the exception dialog.

Thank you for the bug report. Could you please try version 5.2.33. Thanks.

Apologize for not checking for a newer version.
I am still seeing the exact same behavior with 5.2.33.
I have attached screenshots.
The array out of bounds exception...
Could this be referring to the tabs array?
If you look at the step2.png shot, when the exception happens, the tabs get hammered.
When I click OK on the exception dialog, the max(id) result is shown (but the tabs are still whacked).

Thank you for the feedback. Verified as described.

Fixed as of 5.2.36:
+        Manipulating multiple SQL editor tabs would sometimes result in
+        uncaught exceptions.
