Just a bit of a warning.
This might be a glitch specific to my install, or it may affect others.
Downloaded and installed sp 4.0 this afternoon. Immediately afterwards i am unable to bring up files via windows indexed search function, including files unrelated to SW. I checked the indexing option and all the folders I've selected to be indexed (my documents folder and a number of job specific folders) are cleared now and only "SOLIDWORKS DATA" is listed as an indexable folder. Even "documents" and other windows defaults are gone.
This is kind of a drag since I was set up to easily access job folders by pressing windows key, followed by job no, but now its broken until windows gets through reindexing of my job tracking folders.
