DCS stops working after exiting training.....

[Conuk]

loads fine... I hit some training... working... I quit....

 

box comes up DCS has stoppped working on desktop .... I click cancel.... simulation goes back to main menu ?

 

No mods installed... and pretty fresh (as in a week) OS (vista 64) install... latest gfx etc drivers installed.

 

I guess not a major issue but the pop up box is annoying.

 

Any ideas ?
