HTTPS redirection of admin URLs causes popup problems - Joomla! Forum - community, help and support

i have site set such /administrator/... urls redirected https. when this, following happens:

from article manager, if editing article tinymce 2.0, , click on icon @ top insert image, popup comes up, contains absolutely nothing inside it.

if turn off redirection (rewrite... directives in apache config below), on http, , popups work correctly.

does have idea doing wrong preventing editor appearing when click on icon? (the behavior same popups, not image-editor)

using joomla 1.5.15, running under apache -- apache config looks like:

<virtualhost *>
servername xxxx.xxxx.com
documentroot /home/xxxx/public_html/xxxx
rewriteengine on
rewritecond %{server_port} ^80$
rewriterule ^/administrator(.*) https://%{server_name}/administrator$1 [l,r]
</virtualhost>

<virtualhost *:443>
servername xxxx.xxxx.com
documentroot /home/xxxx/public_html/xxxx
</virtualhost>

thanks alot ideas!
