The program is Office Hours Pro, Medisoft/ on MF 1.8/Win2000. It runs client server with a mandatory 100mb connection to a database server running a service. The help screen on this program flashes (strobe light effect) and sucks CPU time. If I click on a bullet on the screen (i.e. like in getting a highlighted word defined) the screen stops flashing. Obviously a program that sucks up to 25% CPU time when using help is not good. I can disable help if I have to! I'll obviously (like that word) call the vendor and see if they offer something brilliant-which I do NOT expect. I've also got to test this on a standard W2K box and non citrix 2000 server to see if the strobing/CPU time is still there. I've seen other programs with this effect/ any hints on taming it? *********************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link. http://thethin.net/citrixlist.cfm
