Try this:
- Go to Options -> Online
- Set "Toad Improvement Program" to No.
If that doesn't help,
- With Toad not running, edit your Toad.ini file (steps to find it here)
- Add this line under [SETTINGS]
InternetAccess=0
If that doesn't help,
- turn on tracing by adding this line in Toad.ini under [SETTINGS]
DEBUG=1 - Run Toad
- Find the file User Files\logs\ToadDebug.log
- Post that file here.
