Visualisation of GEOPAK data

Hi, We are currently using PowerCivil for Americas V8i V 08.11.05.39 and are noticing significant delays in visualising the data (small datasets - less than 300 points) It is not GEOPAK slowing things down - it does it's calculations then goes to visualise the data within the MicroStation view (or PowerDraft version of anyway) - this is were the delay occurs. It basically appears that that the program has 'hung', but waiting a few minutes, the data re-visualises. We have checked "Task Manager" and PowerCivil is not using large amounts of CPU nor RAM - very minimal amounts actually! This did not occur in previous versions of the GEOPAK software (we previous were using PowerSurvey XM V 08.09.06.31). Is anyone else experiencing this or know of a "fix"? Cheers, Chris.
