It seems that ksnip is unable to capture cascading menus like this one for example:

I tried these commands:

• Capture active Window
• Capture Window under Cursor

Capture active Window captured nothing (blank image).
Capture Window under Cursor did nothing (nothing was captured).

Can ksnip capture such menus? Am I missing something?

I am using ksnip version 1.6.0 under Windows 8 x64.
