> Hi,
> I'm using a mac version 10.9.5 - I've recently updated Fiji, and ever since
> then, it either freezes completely, in which case I have to force quit
> Fiji, or it runs extremely slowly, both with the graphical user interface
> and the scripts.
>
> The version of ImageJ which is giving me a hard time is: 2.0.0-rc-43/1.50e,
> build: 49b667f9aa, Date: 2015-11-20.
>
> I also get warning messages from the console:
>
> [INFO] Reading IFDs
> [INFO] Populating metadata
> [INFO] Checking comment style
> [WARNING] Expected positive value for PhysicalSizeX; got 0.0
> [WARNING] Expected positive value for PhysicalSizeY; got 0.0
> [WARNING] Expected positive value for PhysicalSizeX; got 0.0

> What can I do in order to be able to work with Fiji again?
