I'm using Version 4.0.424 on the Windows 7 RC1. Recently the only way I can view the window is to view it maximized. If I try to use it on the "restore" setting it goes to the taskbar and won't show at all. This is a minor annoyance really. The only reason I prefer the "restore" view is because I like to keep an eye on my CPU Monitor gadget. I am still using a single core processor and can't multitask well. My computer's needs have to take a back seat to the family's needs and desires. I think it's probably because of something in the o/s. It wasn't doing it in the Win7 Beta. However the ESS window is the only program with this problem. I was just wondering if anyone else has run into this.
