problems loading multiple samples

Hi,

I am trying to write a simple Sample Pool to load in multiple samples and play them. (See below).

I'm using     CocoaDialog.getPaths
and then     Buffer.read
to get them in.

this works fine when you are loading 1 sample at a time but when you select say 10 or more at the same time and try to load them supercollider crashs. It also crashes when you try and play them.

Am I doing something wrong?

    var server, sample, name, filename, pitch, amp, window, rect, gT, gL, gH, gW, sampleListGUI;

Try increasing the maxSize argument to getPaths.

If you select more items than maxSize specifies, crashes are likely. But, I'm surprised this happens with just 10 files because the default is 20.

When I have some time, I'll make this more explicit in the help file.
