Measure/Charge Tool Freezes Materials Studio After One Use

Hi all,

We just upgraded all of our computers in our lab to Windows 7. After upgrading to Windows 7 and installing Materials Stuido 5.5.2 on all of the computers, on two of the computers (which are identical computers) after using the measure/change tool to measure between the distance two atoms, it doesn't allow a second measurement. Also after one measurement is made it treats all the atoms together as one, ie you click on one atom and the they all become selected. We have tried multiple files and created new files in it and the same problem exists. On the other computers that we have upgraded to Windows 7 with Materials Studio 5.5.2, this tool works fine.

We have tried uninstalling and reinstalling Materials Studio and the same problem exists. We have also installed Materials Studio 4.4 and the same problem exists.

Any help would be greatly appreciated.

Matt
