vworkspace flash acceleration host (x86) has stopped working

Hi,

We have a few users that use various shopping sites for their role (ebay, amazon, sainsburys etc) and when accessing these sites in IE (IE11.0.9600.18860) it hangs on he login pages and then we get an error 'vWorkspace flash acceleration host (x86) has stopped working' and we then have to end task on IE.

This only happens when using the AppPortal connector 8.6.309.4227, when we try using standard RDP we don't get the issue.

Thanks for any help!

Dan
