Hi, I am having a strange problem with the scroll window of envi. When I want to maximize it, it first becomes tiny and goes to one corner and then after about 10-20 secs it maximizes. Then when I want to link two windows that also takes about 20 secs before the link window opens up. It was not doing this before. Does it have to do something with the memory of my laptop. I am running envi on a 64 bit Windows 7 operating system with 4GB RAM. Any kind of suggestions will of great help. Thanks very much, Tilo
