Hello,

Something i often use in my drawings is to use a dashed circle as a viewport object for details. This usually works with no problems at all. However i this seems to have stopped working, even in previous files where there was no problem. Object viewports still seem to be working with a circle, but just not when dashed. 

Strangely, i am not able to enter the model space through the viewport. I get the flash of the drawing in model space when the 'viewport' is created. but then nothing seems to work going forward. 

The only thing i can think, is that it is due to the update i installed this morning.

Any help or suggestions would be greatly appreciated.

Thanks.
