In the last few weeks I’ve had several occasions where my artwork disappears as I’m manipulating it or zooming in. A few times the entire image (artwork and material) disappears and I just have a white background. (Last time it occurred was at 22:37 hrs tonight.) I know there has been similar issues with Safari, but my Firefox has been rock solid up to now.
I am able to work around the issue and don’t really need assistance with my particular unit, this is just an FYI for support as I’m going to assume I’m not the only one experiencing the issue.
