[Newbies] self executable with squeak -- pause on startup

[Алексей]

Hello

First week with squeak :)

I have one (really not one:) question. When I start squeak by
clicking on squeak.exe, I get pause about 15 sec. Then if in
folder only one image file squeak starts with it. If I use
somthing like 'Squeak.exe my.image' squeak startups immediatly.
I must always use '.bat' files for applications?
Or exist way to do this with more style?
Where is problem? I don't think it is so expensive for VM to
find image file(s).

Alex.
