Changing gloss precentage directly crashes Rhino

I have been seeing another issue with changing the gloss finish percentage number in the Material menu. Changing the number by selecting the percentage directly and typing in a new number results in a crash. Using the slider to change the number works without problems - but is a bit slower and less accurate when trying to match a percentage jbox_cover.3dm (547.3 KB) number to another part or object.

The Object Properties > Material > By Object panel has problems in the current WIP release. This will be fixed in the next WIP release.

Yea Ive been having the same problem but the slide bar still crashes mine at high levels of gloss. The reflection does the same thing
