installshield and Wine

What is the current state of play?

It seems that InstallShield is pretty much and essential element in a  
working Wine env. But I tried to install Dragon NS 7 yesterday and it hung  
completely with a system wide modal in the middle of the screen.

I had to kill the parent.

There has been some regressions in Wine recently it seems , what would be  
the best wine version to install to get around this issue.?

Thanks.
