Hi JimSong.<br />
Sounds like your MTS is having problems.<br />
If you're getting a message box every time you try to do anything to your client exe telling you to Switch To or Retry then your client exe is still waiting for your MTS object to respond.<br />
There are lots of possible reasons for this. Obvious ones include security settings and the possibility that your MTS DLL has hung.<br />
Have a peek at the objects on your MTS and see whether the component is active and In Call.<br />
The Transaction Explorer is under the Option Pack menu.<br />
<br />
Most importantly, if you wait long enough your client will generate an error. If it handles it properly and you can get the error details that will set you in the right direction.<br />

Ensure that your DLL does not include any .Show vbModal or MsgBox code.<br />
This will result in behaviour you report.<br />
I don't think that MTS does actually have a problem, but this is not impossible at all...<br />

MTS &amp; VB

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
