We will test.

Also for the record this was an incorrect conclusion:
We identified a problem where there was an invalid pointer being used, when more than 1000 graphics objects of a particular type were being allocated. This would be a very uncommon condition. We do not know if it is the source of the problem or not.
There was not an invalid pointer. There was not a problem to begin with. This was simply an observation that was never actually tested. Testing showed that there was a correct pointer at all times.

In general, the only things we have identified, is failure to check for memory allocation errors in the graphics related code and other very exceptional conditions in some areas of OpenGL related code. But when it comes to small memory allocations which are the vast majority of them, those do not need to be checked because if something like 10 bytes of data cannot even be allocated, Sierra Chart cannot even function to begin with.

We also tested one of your other Chartbook's which was encountering exceptions (MAIN.Cht). After four days of testing using OpenGL there just was no problem at all. Completely stable. Once again completely stable and no issues. So as time goes by, our original belief that these are system specific issues and the problem lies elsewhere outside of Sierra Chart is proving to be correct so far. Now we could invest in the same hardware that you are using and the same driver and find out what we discover but it should not matter.
