You guys should make a easier way to submit bugs on your website. It might be more encouraging for others to submit their bugs

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Hi @JamesDean3

Could you share the gif that causes exception? I published a pre-release build for testers / contributors, you can download it here https://github.com/d2phap/ImageGlass/releases/tag/2.1.0.0
it may be fixed.

[JamesDean3]

Here is the gif that caused the problem. The build you linked works properly.

[d2phap]

Ok! The problem is your animated image ends with .jpg, instead of .gif.
The pre-release build fixed this issue.
Thank you :)
