Eddy,
sorry for the 'false alarm' here!

My first trial left me with no icon toolbar showing up!
But right now i retried (disabled v2 and put v2.5 back into Plugins folder).... and it works!

CamBam's trying to fool me.

@David: it's win7 x64
And one other thing that came into my mind while having the 'fit to selection' icon working nicely:
Wouldn't the 'F' key make a nice shortcut for this function?!
