Hi, every expert

 i have tried most of new versions, as follows, but there are qdec  problems that I cannot change value in the text box. I know that Fedora  (fc20.x86_64)  20 (Heisenbug) mismatch with these versions.I want to know which version of Fedora you use successfully without qdec problems.

freesurfer-Linux-centos6_x86_64-dev


thank you very much.
