With windows as manager you open a xwindow terminal session with windows managing it as if it were a windows application...
Now Reflection is V14... 10 was buggy and dates from NT4 period...
You should at least be in V12... (Includes SSH...)
If you are running NT4 then you have in Reflection utilities a mutidesktop manager, that will be your solution: Desktop 1 : Windows 2: X
Then you configure:
Window Manager Settings -
* X terminal desktop
Default window manager -
* None
