Lunchbox: Object Save freezes Grasshopper UI

(I have posted this also in the Lunchbox group and written directly to Nathan Miller, but never get a reply)

I have been using the Lunchbox Object Save component for a bit now and adding to the previous bug with the object colors (http://www.grasshopper3d.com/group/lunchbox/forum/topics/bug-in-lun...), I have now come across an even more annoying bug.

If I save some meshes as a .obj file it completely freezes the Grasshopper UI.

I have tried the attached file on 2 different computers with the same result.

In the attached file make sure to have a valid path to an existing folder (eg. your desktop folder) or it wont save.

Only unloading and loading grasshopper solves this. Zooming in and out of the Grasshopper UI with the mouse wheel still works, but all other clicks dont register anymore.

Please help!

I am using the latest GH and Rhino 5 SR11 on Windows 7 64bit.
