Preview doesn't work

Helo,

I’ve already post in the French Section (http://modxcms.com/forums/index.php/topic,3292.0.html), and there is no solution yet. So I post here to have more chance to solve the problem.

When I edit a document, the preview tab doesn’t seem to work. I’ve check the configuration panel to activate it, and the window is still blank.

I’ve a temporary solution in the French Section (thanks to Guillaume)

It seems to be a refresh problem of the preview panel. If I switch to another panel and come back, the preview is shown.
This another point to solve in the manager update.
