More information When my VS2005 is running slowly, I checked my Task Manager/Processes tab. And the devenv.exe was using up loads of memory. At some point in time it shot up to 1,000,000k!!!! It started of with around 200,000k and steadily went up Is that the reason why it runs so so so so slowly? But with 1Gb of Ram and 2.0Ghz processor I'm still baffled why it runs so slowly.
