update problem with flowcharts

we have updated to picaxe 3.5, and can not draw lines in flow charts.
Is there a .dll file that needs installing on the C:\ drive of each machine on the network in order to run the flow chart section of the program.
It runs OK on the network technician's machine which runs as like a stand machine.

 

Yes make sure the file flpcad.dll in the Windows system folder is updated and registered correctly (register using regsvr32.exe if not using the standard installation)
