I've looked a bit more into this and it is so that Wine supports two 
approaches:
* run 16-Bit executable natively (basically the same that Windows does)
* if that fails (e.g. on 64-bit Linux) run the application in DOSBox

So in the first case the application might correctly interact (and 
display) like other non-16-bit applications, but in the second case the 
application will be emulated and thus the application will not integrate 
as nicely as in the first case (especially if it is a graphical Win3.11 
application which also might require that you set up your DOSBox correctly).
