I have been having an issue that happens from time to time, across multiple versions. Occasionally when I open an image in any HDD, Imageglass will not open and my HDD will start doing a repeating loud sound, as if attempting to read something and failing. It gets stuck like that for a bit. Trying to close the program on task manager doesn't seem to help. And during a period of time where I attempted with using alternative software, that issue never happened again. I also can manage to open those images with other programs even when Imageglass causes this issue.
I really have no idea what could be the problem, this by far has become my favourite image viewer for a long list of reasons, and no alternative I could find manage to fit all of em, so I really would love to know what could be done about this to stop it from happening.
