The FogBugz plugin attempts to load and authenticate immediately on launching Visual Studio. We VPN into the company network in order to access the FogBugz/Kiln, which means that frequently the plugin's attempt to authenticate fails. The plugin then launches a modal login dialog which sits atop every other window on the system.
It would be great if this behavior were configurable, allowing a login failure due to URL unavailability to occur "gracefully". Visual Studio could load, and the plugin could display a simple login link.
