Hello,

We've investigated the problem more thoroughly and found out that such behaviour is connected with the specificity of the dll work.
It is not correct to set connection on DLL_PROCESS_ATTACH and break connection on DLL_PROCESS_DETACH, because on DLL_PROCESS_DETACH the process created by DataModule still exists, but the stream probably does not. That's why a more rational solution will be to create two methods in DLL – Connect and Disconnect – end set and break connection explicitly using them.
