Wild media server (UPnP, DLNA, HTTP)

Hi this is what happens to me.

After updating the index as soon as i click close on the folders archive page. The "External subtitles module initialization" starts hanging the program for a couple of minutes at the least.

Here is the question:

If this is a necessary step why it isn't done automatically at the end of the scanning. I leave the program updating the index only for having to wait more minutes as soon as i come back.

Thanks
