Because sometimes Windows just **** ups and prevents Pharo from loading some libraries, including Font, and in such cases Roassal also doesn't work. But restart (or two) so far as always fixed it somehow magically.
No luck. I cannot say whether this fixes the problem on Windows 7 because I'm
not at work. But roassal will not install on my Windows 10 laptop.�� Other
items from the Catalog Browser install OK. So it's a problem with Roassal in
particular.
