Hi John
I purchased ES3 and as you know it comes packaged with Coreldraw X6.
When I first encountered the Coreldraw issues (there are more than the disappearing menu bar), I contacted Wilcom and asked the specific question about compatibility of X8 with ES3. I was informed that the integration wouldn't work as ES3 is designed to work with X6 and that's it!
Yes, I'm p*****d off with Wilcom too as their solution to the issues I've experienced is to buy ES4 or whichever is the latest version). I don't know which version of Corel comes with ES4.
