Switching over

Any problems reported on users switching over from Xara Designer Pro X 15.1.0.53605 to The latest version?
File issues, compatibility etc....

Also I am about to work on a 40 page website desktop for now version, Will Xara designer pro x15.1 do as far as
memory usage? I have currently

Memory Usage 43 %
Total Physical 3.50 GB
Available Physical 1.97 GB
Total Virtual 8.38 GB
Available Virtual 6.78 GB

Are you running a 32 bit system?

4Gb of memory seems low by today's standards, and you may see some memory errors or drastic slow-downs if exporting a large website on a system with relatively small amount of memory.
