In Snagit 8.2.0 there does not seem to be any way to capture a tools type drop down menu. When you get the menu ready and click back to Snagit, Snagit becomes the active window. Of course, this means the menu on the screen you want to capture is automatically closed and you can't get an open image of it.

In order to do so you have to add in an extra step. Get your menu ready, press the PrtSc button. Open Microsoft Paint or similar and paste the result, using Ctrl V or the edit menu. If you use a photo package your screen shot quality won't degrade as it will if you copy directly into Word.

At this point you can click the capture button in Snagit and select the menu region as in the example above.

Snagit is a very nifty screen capture program from TechSmith, very good for creating documents quickly, or for editing, annotating or sharing your screen shots. It's priced at $39.95 for a single user licence.
