Subject: 8-bit image strange thresholding.

Hello.

I am using Fiji, latest edition on Mac OS X.

When I did the thresholding of 8-bit grey image before (and also now on other machines) by default the threshold, for example, like (0;100, B§W) detect everything which is darker then "100", and makes invisible (white) everything which is above that threshold.
After working with other Java-based program (GemIdent), the threshold in Fiji works strange. If using the settings: (Default, 0;100, B§W), then everything which is darker then "100" is turned to white, and above 100 to black.
This is nor Fiji bag, because it works fine on other machines. And I reinstalled Fiji and Java 6 with no result.

Does anyone knows how to fix it?

Artur
