  Hello again listmates,

If I try to convert 16bit color images into 8bit grayscale by doing
"image>type>8bit" I get an RGB stack instead.

The way I found around that is doing "image, color, stack to rgb"
followed by "image, type, 8bit".

Shouldn't I be able to convert directly? Maybe its a bug...

Also, I tried to apply the batch converter plugin to convert all the
files from a folder to 8bit-TIFF and this is what I get:

java.lang.ClassCastException: [S cannot be cast to [B
