Yes.

Also another tip, if you meet the same with a binary distribution and you  
do not have the source or don't want to recompile (because too complex) :  
open the binary in an hexadecimal editor, go to 16#3C#, get the two bytes  
words located there, add 16#5C# to that two bytes word, and go to that  
address (the one resulting from the sum). There, you will see a two bytes  
words which is probably set to 1. Set it to 3 (and save the binary file),  
then no more console will be opened at the application startup.

Note: some times, this console may display relevant informations about  
what's going on, especially at startup. If the application is not well  
tested or is a kind of beta or alpha, it's better to have a console and  
not to get ride of it.
