I had a look through the Shell.explorer methods and I didn't seeanything (obvious) that would allow you to zoom the contents except for ExecWB so I'd try that first.

Another "trick" that might work is to send the Ctrl+ and Ctrl- keystrokes to the explorer window. That one's a little trickier. i could try to make this a feature of ssCore.Browser but it would take some monkeying about (so no guarantees).

Your trial version never expires, the only limitation is that the EXEs you build will only run for 1 day after they are first installed. So you don't have to worry about the trial version expiring before you get everything figured out
