Comment 6 for bug 806804

I noticed that this problem is more clear when the session has slides attached with it, if the slides are gonna take like 10 or 15 seconds to download, lernid freezes for that long till the download is finished, what's even more annoying is that when i closed lernid and reopened it it had to download the slides again, guess it was more clear with me cause my internet connection isn't that fast.
it would be good if we downloadin in /tmp and check if the file exists before downloading, it would be nice, but for the whole freezing thing i think it won't be possible to solve without creating a separate thread ( i think )
