Description:
when running a scheduled backup on MYSQLAdministrator, the backup does not run and gives the Application error : 
the instruction at "0x005b1fc3" referenced memory at "0x00000008". The memory could not be "read".

Followed by : Exception EAccessViolation in module MYSQLAdministrator.exe. Read of Address  00000008

if I run the backup manually it runs fine

How to repeat:
with MYSQL version 4.1.1
schedule a daily backup on MYSQLAdministrator

Suggested fix:
???

I was unable to reproduce this bug using 1.0.21.

I have the same problem. The backup executes manually but not scheduled.

Application popup: MySQL Administrator: MySQLAdministrator.exe - Application Error : The instruction at "0x005c9b4b" referenced memory at "0x00000008". The memory could not be "read".

Click on OK to terminate the program
Click on CANCEL to debug the program

Clicking CANCEL gives no additional information.

The application log has a DrWatson event 4097

The application, C:\Program Files\MySQL\MySQL Administrator 1.0\MySQLAdministrator.exe, generated an application error The error occurred on 08/05/2005 @ 23:23:29.625 The exception generated was c0000005 at address 005C9B4B (MySQLAdministrator)

MySQL version is 4.1.12a
MySQL administrator version is 1.1.0-rc

Forgot to mention the OS is Windows 2003 SP1

We had a similar problem on one of our servers:

Windows 2003 SP1
MySQL 5.0.37-community-nt
MySQL Administrator 1.1.19

As above, I could run the backup manually from Administrator, but when I ran from scheduled tasks I got a similar "The memory could not be read" error.

This was resolved when I upgraded to GUI Tools for 5.0 (i.e. Administrator 1.2.11).  I had to uninstall the previous version and completely reboot before it worked though, but it seems to be fine now.

Hope this helps someone.
