Conemu suppresses launch of an OpenGL application

Question

Getting tired of the terrible cmd window, I found ConEmu which turned out to be a great replacement... except it suppresses the creation of the OpenGL window when I double-click launch the exe (I have ConEmu take over the normal cmd window completely).

If I launch the exe by going to the folder through ConEmu and typing out the name testOpenGL.exe then the application window launches properly.

It would be great if anyone has come across a similar issue and knows the solution.

The window itself is empty because nothing is drawn (wanted to avoid sharing assets), but it shows up. That is, without ConEmu the console shows up as well as the window with an OpenGL context. Double clicking and letting ConEmu handle the console output does not spawn the window. Running the app manually through ConEmu by using the command prompt running the exe fixes the issue.
