We are teaching Tuxpaint as a part of our curriculum for Grade 1. We have a lab of computers with the following configuration:
Ncomputing Vspace Server+9
Windows 7
Earlier  we were using windows XP. Then it was working perfectly but after we switched over to Windows 7, Tuxpaint is working only on a few computers. When we start Tuxpaint on the other systems, the program hangs up and "Not Responding" message is displayed.
Please assist us in resolving this issue.
Regards,
computer teacher
