Generate a Growl Notification on Menu Item / New Window

I'm looking to set up a growl notification when a particular window within that application opens, either via a menu selection or via a hotkey.

The growl notification is intended to remind staff to enter all relevant information into that window before saving it.

At present, I have the macro always active in the application, and it triggers when the application launches.

The macro pauses until the front window of the application shows the relevant title.

This appears to work, however I expect it can be triggered more easily.

I wasn't able to trigger the macro effectively via the same hotkey that opens the menu item - the growl notification popped up easily enough, however the actual menu item didn't work.

If you can give me any advice on how to better structure this macro I'd appreciate it!
