Hello Bruce
thanks for your answer.
Yes, the application is ABC and multi dlll, in addition, I use nettalk in 4 Dll including the DataDll I explain a little:
This app. was working finr with C8, then I upgraded it to C10 and I'm using NetTalk 8.71 basically Netsimple (client and webclient classes)
The problem is that the app. fails at the end of each thread (all use NetTalk or not), generates an exception error, and I went through the process of checking my code at the beginning of the program, especially the string slicing and values out of range, I used the debugger but it does not give much information, except that the exception is generated after ClaRun makes a call stack and before there are some call stack of ClaNet, in the forum of SV I was told That probably the exception is related to the link mode for nettalk, I transcribe the commentary of Diego Borojovich:
"There is not much information on the screen you post.
My educated guess is that you have wrong the link/dll mode settings for nettalk
in one of the multi dll app, posible the datadll.
Other than that check if you have their last version or how to set it up on a
multi dll app.
Usually a bad link mode fail on the thread start up, but I never saw the
nettalk cade to see if it properly coded."

Thank you very much for the support.
