Just uploaded a new script for quickly switching back and forth between different projects folders. They were new in 3dsmax and allow for relative path names (so you can quickly move an entire project to some other folder). Unfortunately, there is no history about previously used folders, and I my projects are deeply nested on the network so I wrote that script to be able to switch between the projects without browsing the entire network structure.
There seems to be a small bug in 3ds Max 2008. It causes projectSwitcher to always show a
Browse-Folder-Dialog when swichting projects. This can be fixed by manually editing the file Macro_SetProjectFolder.mcr in the <3dsmax_root>\ui\macroscripts directory and changing
in line 25 and 26 to
Save the .mcr file and restart 3ds Max. This should return normal functionality for projectSwitcher
