I installed .net4 on all-----both main and clients.

Did notice that if the traffic in the office network is more- with all staff logged in - the network gets slower, especially the medication and imported items pullups.

When I am working alone it is faster in computer with 2 gb ram/faster processor vs workstation with just 0.5 gb ram/slower processor.

I did try the hardware accelerator turn off- at first it seemed to make a difference, then it did not.
