[SEVERE BUG] ExtFS for Windows changed all my files permissions !!!!!

[a.ster]

Hi, I am trying ExtFs for Windows to access my Linux partitions.
With it I have mounted my partition as read-only.
When later I have rebooted my Linux OS I have discovered that all my files are read-only (with the 'write' bit off)
I had to fix all my files by doing

for p in $(rpm -qa) ; do
   rpm --restore $p ;
done
chmod -R u+w /home

Please FIX the software, which for me is USELESS because it changes my files' permissions.

EDIT: after I fixed my files I booted again in Windows and mounted my home partition read-only.
Now I have rebooted in Linux and AGAIN the files' permissions are read-only.
