problem in selection

[thezippons]

Hello, everyone! I have a very weird problem. You usually use the mouse to select lines or objects drawn. . improvising when I click left button of the muose to select does not leave the green curtain anymore and consequently I can not work!!! How can I solve this? thanks in advance

green curtain?
but do not recheck anything or simply not seeing the curtain (perhaps selection area) are you in trouble?
anyway in the second case http://www.cad3d.it/forum1/threads/33201-ripristinare-l-area-di-selezione
