Kovid, this may be for your FAQ section:
It is necessary to adjust settings in your AntiVir to make Calibre trusted software without any application restrictions.
That's what I did and Calibre is responding better, faster ond without majour hickups. I will monitor this further.
Request though, possibility to extract info into the table for LRX files. Basically would like to have them with similar info as non-DRM files. (dreaming
Thx
