Capture Internet Explorer option from System Tray only works once

Capture Internet Explorer option from System Tray only works once, Greenshot must be restart before it will work again.

Steps to reproduce:
1) Click Capture Internet Explorer option from System Tray on an IE webpage that has content that must be scrolled
2) Repeat step 1

Expected Results:
Option should capture the same image and write to a file

Actual Results:
Second time selected, Capture Internet Explorer popup displays but no image or dialog to save image is displayed

There is a work around by closing and restarting Greenshot, however this is extremely annoying and time consuming when needing to capture several extended screenshots.
