Open Next on sample images is still behaving wrong

Stein Rørvik
Thanks for the fix, which works as advertised.

I found that there is still a related bug appearing when using the Open Next on dissimilar image types.

Try this:

- Cache the sample images if you did not already do so.

- Open "Organ of Corti"

- Use "Open Next"

- The "Particles" image opens correctly

- Use "Open Next" again

- The "T1 Head" stack is opened wrongly as a 4-channel stack, same as "Organ of Corti"
Apparently the multi-channel type got stuck.

Similarly, if you start with the 2-channel "Confocal Series" and continue with "Open Next",
the next stack in the samples image folder ("Fly Brain") is also opened as a 2-channel stack.

If you start with the 1-slice "Particles" image, the behaviour with "Open Next" is different, but still wrong:

The T1 Head stack is then opened with the wrong canvas size.
This only affects the view, if you e.g. do a duplicate on the image, the result is correct.
Apparently the canvas size of "Particles" got stuck.

The first bug is a regression; it did not occur in 1.52e. The second bug was in 1.52e too.

I am using daily build ImageJ 1.52g on Windows 7 64-bit.

The latest ImageJ daily build (1.52f29) fixes a bug in the File>Open Next command that caused it to not correctly open a non-composite image after having opened a composite image.

These bugs are fixed in the latest ImageJ daily build (1.52h4).
