I have just installed 3.4.15 side by side with 188.8.131.52
I did not copy settings.
I opened an Oracle 9i model created with 184.108.40.206 and saved it.
When I try and close the workspace, I get a totally empty confirm dialog and the TDM window goes blank.
If I click on the popup it changes to Confirm(Not Responding) or Toad Data modeler […] (Nor Responding).
Closing the popup window (with the x) give the Windows End Program dialog.
When I restart TDM, the model reloads and the problem occurs again.
How do I resolve this?
The PC is Pentium 4 3.2GHz Dual Processor with 2GB RAM running Windows XP Pro ver 2002, SP2
