Hi Mic:
TencentQQ is the most social software in China. But the input method don't be read when inputting on it. I contract the Tencent company to solve this problem. When they try to add NVDAHelpRemote.dll to the safetyList, TencentQQ will be crashed. I've get the stack dump information here. Please fix this BUG as soon as possible. Thanks very much!!

From what i can see from this stack dump, this crash occurred after the application explicitly chose to exit. Regardless, this is something we obviously want to fix, but it's not quite as major if it only occurs when the application exits. If that isn't the case, can you please explain when the crash occurs; i.e. as soon as NVDA is loaded or is there some specific action that causes it?

Hi:
If this bug cannot be solved, then NVDAHelpRemote.dll will not be added in their safetyList, so NVDA will not read input method on it. However, more people will not install NVDA on their computer. TencentQQ in China is Skype in the world. Most of all people cannot leave it in their live. I do hope this problem can be solve now. I create a website to expand NVDA in mainland China. I believe more and more people will use NVDA and they will contribute their codes for NVDA. I am studying Python for this reason. If you want to know the website, please visit:http://NVDA.qt.hk/
Thanks very much.

Fixing crashes is of course important. However, you didn't answer any of my questions. Tracking down problems relies on reporters answering any questions we ask of them.

Hi:
I am sorry. I delete the answer accidentally.
The case is the same you said.
QQ will crash when it is exiting.

Is it possible for us to run this modified version of QQ? It's going to be pretty difficult (if not impossible) for us to debug this without access to the software.

Hi:
It's OK. But it is a simplified Chinese software. Can you know Chinese or what information do you need?

Is reproducing the crash as simple as opening it and closing it or do you need other steps to reproduce it? If it's that simple, we can hopefully get by without knowing Chinese.

Hi:
I have asked the developer. Exiting the qq will cause the error. System: windows xp 32bit

@vgjh2005 Does the reported crash still occur with TencentQQ and NVDA's latest versions?
