M2Mstudio hogs the COM port even when not connected!

I can confirm the above behaviour,

another route to the same result:
[list=]Start M2M Studio – it “grabs” the COM port, even though it’s not using it;[/list]
[list=]Open SeLiMa[/list]
[list=]Close the opened port[/list]

I get the feeling that this behaviour is caused by selima?
because all the old tools also open the com-port the moment they’re started.

Also just as a pointer to another option.
the mux-config tool is also very handy for connecting m2m studio and hyperterminal (or other software) to the same module
