Hello Rick,
Here is a message from LTP support:
We discovered that a lot of users have Data Execution Prevention aggressively set within Windows – this causes a problem for many applications using DLLs and is best switched to monitoring Windows services only. You can, of course, keep the system enabled and just opt to tell Windows which applications to exclude but that can become annoying after a while.
The easiest way to change the setting is to go to Control Panel and select “classic” view. Now go to System, Advanced Settings, Settings, Data Execution Protection.
If your version of Windows is set to the lower option then we suggest changing it to the top one (Turn on DEP for essential Windows programs and services only) – it will prevent almost 100% of application crashes without compromising Windows in any way though it does require a reboot to begin using the new settings.
Alternately, you can click Add and locate the copy/copies of terminal.exe to exclude from DEP.
Regarding the “orphaned trades” window… if that pops up then you can always just press F7 then click OK to restart LTP – sometimes the current trade list that gets broadcast immediately on connection arrives incomplete – it is the internet after all! – so rather than make a mistake with an order, LTP will set it aside temporarily.
It is only a temporary thing as the list of unmanaged trades will be reviewed each time LTP reconnects to one of our servers (we have the main server in Las Vegas and our fail-over server in Atlanta) and you’ll see the system switching between them when restarting, if your
broker 
connection gets lost, if your internet drops, etc.
hope that help a little.
regards,
LTP Admin
