DrMemory hang up when using C# access database

Hi,

I'm a newbie to use DrMemory to test my program. DrMemory version is 2.6.0, OS is WIN10 64 bit latest version. My test program is using MFC application call C# library. if I calling access database API, DrMemory will hang up when calling this API(Target application have no response, and memory resource will stop to increase, it can not continue to do next step). eg.

```
call Func1()
SqlConnection sqlConn = new SqlConnection();
call Func2()
```
When calling "SqlConnection sqlConn = new SqlConnection();", target application will hang up and can not do "call Func2()" step.

Does anyone know what the cause for this problem? thanks so much.
