Sometimes thats really hard. Because when you short them, the netlist act like 
both are the same net, and when you highlight both are highlighted, like both 
are the same net.
What to do? If you have few warnings in the log, undo undo undo undo until you 
can press the O key (optimize) and you dont get the same warning message.
If you have a looooot of warnings that means that you did a lot of job and a 
lot of undo will suck. IF the nets are not too big (Vcc and Vdd normally are) 
you can do a shift+backspace over one of them and re-route both nets from the 
beggining. When the problem resides in long and well routed nets, thats sucks 
again.
The third option is to delete parts of the nets, pressiong O until you find 
it. 

In the program, there are two ways to improve these kind of situation. One is 
to popup the log window when a short net occurs (the log windows only popups 
once). I think is a easy workaround.
The second is to implement a way to show exactly where the short is. I think 
it is not impossible...
