I keep having a weird problem since starting to use RH 6 + GH .
no matter what file size I am using , each of the viewports will freeze and turning to black when i leave the file open for a certain time ( say 2 minutes or so ) without any action.
after this time the shown view freeze and when i try to move/rotate it the viewport turns to black.
SOLUTION : the only one solution i have at the time to "unlock" the viewport is to change display mode on each of the viewport , 1 at the time , only after doing this the given viewport display will start to work again.
despite I am still able to work this is annoying behavior , any suggestion ?
thanks , Filippo
