When opening or closing the Project Manager, an Access Violation error appears.
If the Project Manager is set to open automatically by default, the error will show when Toad starts up. It is possible to use Toad, but the error is always evident.
This bug occurs if the following registry entry is null:
[HKEY_CLASSES_ROOT\htmlfile\shell\open\command]
WORKAROUND:
Put an entry in the [HKEY_CLASSES_ROOT\htmlfile\shell\open\command] registry entry, and the error will stop.
