I double click on a table to bring up its detail.
Click on the data tab
Right click a column (i.e.: VARCHAR (4000)) that is defined as large and select ‘Fix Column’ -> ‘Left’
Toad pops error dialog.
Exception: System.DivideByZeroException
Message : Attempted to divide by zero.
Sometimes I can recover, sometimes error dialog starts repeating.
Regardless, scroll bar at the bottom is messed up and I am forced to restart TOAD to recover.
