API Performance

[hrs]

Hi,
I have a API application which takes realtime tick data from 30 symbols. I notice if I run newer versions of eSignal for more than an hour the performance grinds to halt i.e ticks are severly delayed and esignal stops becomes unresponsive. I have to revert to version 10.4.1608.596, which at least lets me run the application for a most of a day before I need to restart esignal.
I've been trying to find some information in the release notes, but had no luck.
Have there been some changes to the Desktop API?

Regards

Henry

hrs,

The Readme files would be in the eSignal Directory C:\Program Files\eSignal. If any changes have been made to the API they would be listed in the Readme File.

Other then some changes to the history function the API reamain the same between 10.4 and 10.6.
