Debug activation request

I don't know if it's just me, but I keep getting caught out by the debug icon on the Debug window. When you click it or press Ctrl-F5 to activate a debug session, the icon doesn't become disabled until indexes have been examined, updated files recompiled, and the debug execution actually starts. This means there can be some time between activating 'Debug' and the icon disabling and becoming greyed out.

When I'm busy, I often find myself pressing Ctrl-F5 to start debugging, and glancing at the debug icon a few seconds later to check whether it's activated, and pressing Ctrl-F5 again because it isn't disabled - which causes another debug session to start...

It would be really helpful if the debug icon was disabled as soon as debug is activated.
