this is an issue not only with 2018 but also 2017 Corel will also crash when pasting from one document to another?!
There's not enough information for a proper answer.
For example: it only happens with pasted images? Why is the image pasted instead to imported? what's the size and resolution of the image?
It happens more often when tracing bitmaps as I mentioned in the title.
Yes, but for detect the cause we should investigate if there was any condition or situation that could cause the crash. For example, it happens always when you try to trace images? what's happens if you use a different settings? You mention about "pasting from other document"... it happens if you import the image instead paste?
It happens when I trace a bitmap, outline trace, Line art.it does not happen all the time but it is anoying especialy when it decide to crash and I have other corel documents open that I am working on.
When it comes to copy and paste, this happens when I copy an object from another open corel document to one that I am working on to use the same object from that document.
