Category:	MySQL Workbench	Severity:	S3 (Non-critical)
Version:	5.2.26 CE	OS:	Windows (Vista Business SP2)
Assigned to:	Assigned Account	CPU Architecture:	Any

Description:
Upon opening a connection, Workbench opened the SQL Editor pane then threw an error "Invalid node". The Overview tab did not show the first database, and would not refresh.

How to repeat:
Error has not occurred again, may be intermittent memory fault or network error.

Suggested fix:
Close program and restart.

Hi Dan,
if you encounter the problem again, can you add the stack information to this report? you can gather this information from the err dialog by right-clicking anywhere in the dlg and click the menu item to copy the information to your clipboard.
also the output of help->system info would be of interest

thanks in advance

Will do, thanks.

"Invalid node index"

stack trace info:
Exception = MySQL.Grt.BackendException
Message = Invalid node index
FullText = MySQL.Grt.BackendException: Invalid node index
   at MySQL.Workbench.WbContext.flush_idle_tasks()

(BTW no right-click menu on the descriptive text of the error dialog)
