CodeWarrior 10.4 connected to TWR-K60F120M via USB, using P&E OSJTAG.
On Windows XP starting a debug session was slow but tolerable; from memory about 45 seconds to download and be ready to click the run button. I have just got a new machine running Windows 7 Pro 64-bit (very fast, lots of RAM). Now starting a debug session seems to be significantly slower; over four minutes to get from clicking the Debug button in the C++ perspective to complete downloading and be ready to click the Run button in the Debug perspective. The vast majority of that time is "downloading binary to target" which hangs for a long time at 99%.
Nothing about the target has changed, and this is a completely fresh install of CodeWarrior on the new machine, with a fresh new workspace. Nothing about the project has changed; it was imported cleanly into the new workspace (including the .launch and .pemicro files).
Why would it be this slow, and what can I do to make it faster?
