Love the features of 11 pro, but when I tested 10 pro on my computer it worked and when I went to buy it, 11 was about to release, so I waited and bought 11. 11 freezes when saving, previewing one page or whole and when making adjustments on complex pages. When freezing it gives the option of waiting or closing and usually if I click wait it will become response again and I can keep working, sometimes it crashes. I also turn backup when closing off because the times it crashes it leaves me with an EMPTY file. Thankfully I can use the backup files to restore most of my work.

When testing 10 I used xp sp3 with virtual box on my mac. With 11 I used both Win8.1 and Win10 in vbox. System details below:
With web10 pro I used xp 512 ram 64 vram 32bit one processor - worked fine.
With web 11 pro I tried each of the below and combinations of them for win 8.1 and win 10
1gb and 2gb ram 128 and 256 vram 32bit with 1, 2, 4 processors
2gb ram and 128 and 256 vram 64bit with 1, 2 and 4 processors
also I placed the vbox win drives direct on my ssd drive and on a usb 3 flash drive in usb2 port. While slower via usb, the only other difference is when becoming unresponsive it crashes more compared than becoming responsive again, the opposite of above.

Additionally, thinking it may be a virtual box (vbox) issue I installed 11pro on a win8.1 pc, yet the problem remains. Win8.1 and host mac specs below when using vbox.

mac air 2011
1.7 ghz i5 (3rd gen), 4gb ram 384 vram and 128 ssd 64bit

win8.1 pc
AMD A6 1450 APU with radeon 1ghz, 4gb ram and 500gb hdd 5400 64bit

So, any suggestions?
