Batsound under WINE on Ubuntu 13.04

Well Ubuntu 13.04 'Raring Ringtail' is here, and it makes for an easy upgrade, even on a dual boot Windows 7 machine, my only gripe being that it overwrote my Windows 7 bootloader with Grub-2, the Ubuntu boot loader. Not a problem unless you decide to remove Linux in which case you won't be able to easily boot into Windows. Batsound still works well under WINE but I still haven't sorted out the graphics export problem. The dialogue appears but the resulting image files are corrupted. Not a huge problem since Ubuntu has such a versatile set of screen grabbing and editing tools. I tried out crossover which is a commercial version of WINE to install Batsound.  Again, this worked fine, and now in the export graphics image dialogue box the option to export to .jpg appears but the files are still empty or corrupted. As far as I can tell, all other functions like audio capture and playback work just fine under Ubuntu.
