 * Hi there, even though version 3.6.3 works perfectly, after updating to version
   4 and trying to replace a pdf, I get an error telling that this file has a different
   file type and this could probably make some problems. After rolling back to 3.6.3
   same file is replaced with no poblems

 * Thanx Pedro!
 * I just tested a PDF replace (in Windows, don’t have time at the moment to test
   Linux), and it seems to work now.

 * Thanks for the confirmation, Paul!
 * And thank you all for your patience in getting this resolved, it wasn’t that 
   easy actually, but I’m happy we managed to find a fix.
