In v2124/2125, I hit an unhandled exception in the trade DOM that causes SC to stop responding to mouse clicks. SC continues to run and update in the background, but it can't be interacted with and needs to be killed through the task manager. This message log has this line: Caught an unhandled exception in c_Chart::WindowProc. Message: 513, wParam: 1, lParam: 62062959 To reproduce, - Enter an order with only a stop loss order attached - Add a take profit order - Click on the number to adjust the quantity of the take profit order The exception happens here. After killing and restarting, the order quantity can be adjusted as expected. |

How exactly are you doing this: - Add a take profit order
An operation like this is not supported. It would have to be an individual Limit order that has no association with the Stop. Are you able to consistently reproduce the exception?

It's an unassociated order, not part of an OCO. It's an individual limit order with 'Cancel Orders on Flat Position' enabled in the DOM. Yes, I can do reproduce it consistently and across different systems. |

@User816220 Are you using OpenGL for graphics? Some users - me included - have issues with exceptions when using OpenGL just out of the blue when doing basic UI work. |

No, this is with OpenGL disabled.

This is just not reproducible and does not make technical sense as to why there would be a problem like this.

I still see it running in safe mode. I've been seeing the exception with NQU20_FUT_CME, but if I change the symbol to EURUSD (as the only change made) I don't hit the exception anymore.

It should not matter. We have to do a remote assistance session with you to see exactly what you are doing.

Easy to reproduce, see attached clip from testing this in SIM. Long 2 with bracket orders (Target and Stop). Putting in manual sell, moving it and try to reduce the size to 1. Crash! |

We are still not able to reproduce this at all. We still need to do the remote assistance session.

Tested this under my Windows VM. With OpenGL it crashes (see clip above). With GDI just the interfaces freezes and I needed to force SC to close. While doing that SC asked if I really want to remove chart x, than chart y,.... So I killed in via Task manager. Somehow SC interprets the change in order quantities as a deletion command?

This is not making any sense to us at all. And once an exception occurs, there will be unpredictable behavior going forward from that point. The answer is no to your question.

Not sure if it helps but I was not able to reproduce this on test with version 2111.

User816220: Version 2127 has been released. If you can test, using the simplified procedure that we did in the remote assistance session, that would be good. Let us know if you still observe the same issue.

Therefore our tentative conclusion, that this is a Windows operating system bug, seems to be true. At least the problem is resolved. This issue is so far out in left field and being it is a stack corruption, strongly points to a lower level operating system level issue.

2127 also fixed this issue on my machine.

There really can be no doubt at all, that this is a Windows bug. There is simply no other explanation. This functionality has not changed and has always been 100% solid, and the issue is strictly related to the displaying and repositioning of a dialog window to change the price and quantity. And the fact that it has resulted in a complete termination of Sierra Chart indicating a stack corruption is further indication that this is a Windows bug. Sierra Chart has no such stack corruption issues. We simply removed the code to reposition the dialog, if it is partially offscreen. That is all we did. We maintain our position that the Windows operating system is in a state of deterioration. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

As Sierra is currently only available for Windows I think we need to live with theses issues. But something has changed in versions later 2111 as I downgraded yesterday and could not reproduce this issue. Did not change anything at Windows system. So this dialog windows was handled differently by Windows in prior SC versions. |

This is a completely incorrect deduction. We have extensive experience with this. We cannot take the time to provide technical explanations. The order quantity and price dialog has not changed for like about 8+ years. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
