I've got a fresh install of ArcGIS 10.0, and whenever I try and open a tool from the toolbox (for example, Project Raster) it takes literally 5 minutes to open the dialog, and then at least 30 seconds for any clicks I make in the dialog (for example, to select input files) to register.
Does anyone have any idea why this is? The rest of ArcGIS isn't too slow (at least, no more than normal) but using toolbox tools is just impossible! This doesn't happen on my laptop, and this computer is significantly faster than my laptop (this has 12Gb RAM, quad-core processor etc).
Are there any known problems that might cause this?
