I think you might have to contact Tech Support about it because I can't replicate it here on my machine.

The drawing tool display is slower than you might expect because several of the tools have more complicated display images sourced from a set of mini maps (other very tiny FCW files contained in the drawing tool folder) to help mappers see what they are about to draw, rather than the raw lines and polygons as they would appear without the native sheet effects. Normally, though, this just causes a blinking green screen in the background when scrolling the tools, and hasn't so far resulted in things vanishing the way they appear to have done for you. At least - not on my screen they haven't.

Thank you.

I don't seem to be having any issues with the map itself. Unless Remy or one of the others can find something it is just possible that there is a problem with the app itself.

You mention attempting to reinstall and/or repair something in the thread above. Have you done that as the Administrator, and have you then also reinstalled the most recent CC3 update at the end of it all?

Thank you, Wyvern :)

No I don't think there were any further discussions. I've been a bit distracted with the development of Marine Dungeon in the last couple of weeks.

The stream happened, but we had a few technical issues that were more serious than the usual things that happen in a live stream. We decided that it would be better to maybe redo the video at a later date if time permits.

Meanwhile, the links here and on FB have been removed so that people don't try to follow them to nowhere.

Even 10MB is enough for a fairly large map if you export it right. Use 90 or at the very least 85 'JPEG Quality' and export as one of the JPG options. I exported this map at 4000 pixels on the longest side, and it's only just over 2MB in size. CC3 is pretty good at jpg exports.
