Feed Rate Problem after Upgrade LinuxCNC

Hi,
About a week ago I've upgraded Ubuntu and LinuxCNC (Ubuntu 10.04 to 12.04 and LinuxCNC 2.5 to 2.6). The GUI is "touchy".
Using the same INI and HAL config files, when I started the linuxcnc, the behavior has changed in the following manner: Home command and Jogging worked like in the previous version as I expect. However the MDI commands like "G01 Z-1300 F9000", my Z axis moved extremly slow as if it has been given F100 (i.e. 100 mm/min)!. I changed Feed F1000 to F10000 tenfold but the controller seems ignoring by traversing with the same speed.

To sort out the problem, I have set GUI to "Axis" (it was "touchy") and suprisingly it worked correctly when I commanded F9000. So I pressume there is a bug or some new setting with the new version related to the case when it is set to touchy.

I've also tried LinuxCNC 2.7 but the same problem did continue.

If helps, please find the related configuration files (INI and HAL) are in the attachement of this message.

For this upgrade, I've followed that instructions given in wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6

I found a solution but it maybe informal. I'm not sure.

I edited the following lines;
( I typed 15000 instead of 100 ) in touchy.py

and( I typed 15000 instead of 100 ) in .touchy_preferences file
