Unhandled exception in Sigma Studio 3.5

Hi all,

I get an "unhandled exeption" everytime when I want to connect a Hierarchical input to a T connection. I did this many times before in the project but now it doesn't seem to work ... I already restarted a number of times, went back to a previous version of the project but the issue persists. Any Ideas? I did recently upgrade to 3.5 Build 5, Rev 874, it seems to work in V3.3 Build 0, Rev 672

These are the details:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
