I'm using this beta on a Windows XP SP2 with 1Gb of memory
and Intel Core 2 1.86Ghz cpu.
The application I created is very basic: has only 2 buttons
and nothing else.
If I select both of them to drag them in the design view it
is really slow.
As workaround I noticed that if I close teh FLEX Properties
interface this operation is a bit faster.
I found the overall usability of the interface not so good
for now compared to other development tools.
I hope the speed will improve in the definitive version.
