Upgrading Drupal

After upgrade from drupal 4.7 to 4.7.2 the next message is show in the admin/settings page:

The directory "files" is not writable

¿what is going wrong with this update?

Thanks in advance for any feedback

After upgrade Devnagari characters on my site are all garbled.

Hello, after upgrade from 4.6 to 4.7.2, administer >> IMAGE GALLERIES link no longer there and www.mysite.com/image produces a "page not found" error. I can't find any posts about this or any issues listed: http://drupal.org/project/issues/image?categories=bug All the image gallery categories are in place still and I can reach the individual images with no problem. Just no image galleries.

I am using the Burnt phptemplate.

It seems to me that upgrading from 4.7.0 to 4.7.2 does not need to execute update.php.

I understand this because the two update.php files in 4.7.0 and 4.7.2 are identical

May someone confirm that only replacement of drupal directory files is needed and no change in the DB?

Thanks

Any idea why Taxonomy_dhtml is having trouble with Drupal 4.7 and IE 6? Taxonomy DHTML gives an error on page and parts of the Taxonomy DHTML menu vanish as it expands (not good). Here's the error:

Line 181, Char 5, error not implemented, code 0, URL: http://localhost/mysite/taxonomy_dhtml

What's happening? Any help would be appreciated. I filed an issue report with this project at http://drupal.org/node/68906

I'm getting some pretty severe-looking warnings after running update.php when upgrading from 4.6.8 to 4.7.2. I'm using PostgreSQL 7.4.7, BTW (Debian). Because these are just "warnings", I'm going to proceed, but I don't have high hopes.
