Details

I got some old MRXS files (from 2011) and slidedat.ini had

OBJECTIVE_MAGNIFICATION = 20x

OpenSlide complains:
Unable to open thefile.mrxs with OpenSlide: Key file contains key 'OBJECTIVE_MAGNIFICATION' in group 'GENERAL' which has a value that cannot be interpreted.

Workaround

Changing the line to

OBJECTIVE_MAGNIFICATION = 20

(i.e. removing the x) makes it work again

OpenSlide could recognize both 20 and 20x as valid
