foxmarks/xmarks internet explorer 8 crash

Windows Internet Explorer 8.0 on Windows Vista

Opening a tab using right click "Open in New Tab," "Open in New Window," Ctrl + click causes Internet Explorer to crash, foxmarksdll.dll seems to be the cause.

"Internet Explorer has stopped working"

When this occurs, Internet Explorer recovers the tab, but this appears very frequently, at least for me.

FYI: Disabling FoxmarksDLLBHO Class in the Tools->Manage Add-ons stops this crash in Internet Explorer, doesn't seem to effect synchronization

Also, an extension named "Xmarks for IE..." shows up as unavailable... possibly left over from foxmarks/xmarks change?
