Just tried the version 1.2.8 [5074], it should not be a bug of Zenphoto.

On admin upload page, it use a javascript for a seletion box for upload foloder. Since I have a lot folder, the new array function length is about 11000 characters. Seem the Chrome don't like so long, it will break the line irregularly, so the upload folder can't display properly.

Same case on Chrome Mac or Windows version, but do not have problem on IE, Safari, firefox.

Not much we can do about that I guess (I can't test Chrome as it does not run on my older Mac...). At least you have alternative browsers...:-)

I just change to use Chrome as my default.....

Anyway, seem can't use Chrome to admin the Zenphoto, just found similar case on Album admin page.

I don't think we do anything special there. Maybe a bug in Chrome as is the display of hidden js that Webkit based browser strangely do occasionally. But in case you find anyhing that solves that let us know. Best via a ticket because of feature freeze.
