NT7 hangs on connection on Windows 7 64-bit

[adamus]

Hi,

I've got NT7 latest version running against IB.

When I launch NT7, it starts up fine and loads the workspace with 8 charts and a few simple indicators - no problem.

However for the last few days, it has hung when I connect to IB. I have to open the Windows Task Manager and call "End task" against the Control Center. At that point NT obviously stops doing what it was trying to do and shows the "Save workspace" dialog and after that, all is ok.

I do not trust it to run smoothly after that, so I shut down NT7 and re-open and re-connect and then everything runs fine.

What should I do?

Thanks

Yes, I'm using TWS 921.5.

I submitted my logs and traces to you.

Thanks in advance.

Back again.

I have now deleted all traces of the old strategies that were causing error messages in the event log.

I have a new database .sdf file but I backed up and restored my instrument list and historical data and I am still using the same workspace.

The problem is more severe with IQFeed. I can't actually connect to IQFeed without this problem arising.
