Ok, I'e fixed this in v8.0.1.0. This build Will be issued today. It was a pretty simple case.
If you select to NOT start the GUI at user login after selecting 'Options / General / Reconfigure the way Lasso starts', it will terminate ProcessLasso.exe and *not* restart it (in contrast to normal behavior or other selections). So, you will have to manually restart it.
It's a kludge, but an effective one. It is such because this is a minor update to a stable build, so I must minimize changes. Also, this is an edge case. Most workstation users choose to start the GUI at login, as is the default -- and this problem is only ever seen once, when the user makes the change.
I'll work on refactoring in the next beta series.
However, the larger issue of the process icon *ever* being 'lost', as some unfortunate minority of XP users see, particularly BD users, is something I'm still checking into. That is being tracked in the split thread.
