Hi,
yesterday I installed Silverlight 1.0 and then had multiple crashes on sites that use this plugin. That's with OW 5.7 96113. I have then deleted it and OW is stable again.

I disklike the political dimensions of Silverlight, but someday I might have to use it, so It would be nice if the devs look into it.
I have no idea if the crashes are because of buggy web sites, the plugin itself, or the plugin-OW interaction.
Cheers
