Are you testing with antivirus real-time scanning disabled?

>Well, actual re-compile is certainly not an issue, except that in our environment, where building includes updating Source Control and what not, and installing it for our users, it is much more of a hassle than anybody would like.

>>>Well, actually, I can't do that. I restore the clipboard after using it, so there's no evidence left.

Select(lcExportAlias)

>>Recompile doesn't hurt much nowadays... I remember when that was an excuse to have a break, now it's not worth trying to begin anything else. The app I'm most frequently busy with has an exe of about 20 megs, compiles in 5-6 seconds and my machine is about four years old.
