Unshrinking SDKs on a 64K Apple II+?

[Linards Ticmanis <ticmanis@gmx.de>]

Hi,

I seem to be unable to use Unshrink 2.1 to uncompress SDKs of 140K disks
on a II+. According to what I've read this is the last version of
Unshrink that runs on a II+.

I can boot ProDOS 1.9, I can run Unshrink, I can select the SDK. Then I
get to a screen showing the archive contents and allowing me to select
the (one) disk image inside the archive. Then I go to a screen which
lists the (two) Disk II drives that I have in slot 6 and the volume
names of the floppies currently in them (if any). Slot 6 drive 1 is
marked (inverse). And there I'm stuck. I can press O (the letter "oh")
to reload the list of drives, I can press . (period) to get back to the
main menu, but no other key or combination of keys seems to have any
effect. I can neither move the mark, nor start the decompression. The
list just sits there.

The SDK archive had just been created by Shrink 2 on the very same
computer, by the way, which worked without a hitch. And uncompressing
that image on a PC with CiderPress worked too, so I think the SDK itself
was quite OK.

Is this a known bug in Unshrink 2? Doesn't it really support whole-disk
archives? Or am I just too dense to do the right thing?
