I have installed WC a while ago on a Hebrew WP site worked fine!
I have upgraded WC today to version 2.0.5 And encountered a problem while trying to set up/select any of the pages:
When a page is selected it messes up the 'pages setting' layout and it is imposible to continue and/or save the setting
The whole wp interface disappears and the table of pages is pushed to the left of the page you can not see what is what or save the setting
This problem in not appearing in an english wp site where I have the same version of both WP WC
I have a screen shot of it if the developers are interested in more info on this anomaly
