I have tested the Windows release briefly under XP SP3. It works, but everything lags notably compared to the previous nightly I had installed (7452). I am using MSVC2008 compiler.
For example, I am just testing a small console program using boost. When using 7392 it takes 10 seconds before I see anything in the build log window (i.e. that no rebuild is required) after pressing the toolbar build button. With the old nightly (7452), the respons is immediate.
Even exiting 7392 takes notably longer.
I am really interested in the new release for Linux, due to the new debugger integration. I want to use the same nightlies under both OSes, but the lag issue on Windows is currently a problem.
