When I open an **OTF** or **TTF** file in the app and press any glyph, my computer makes a noise and starts freezing. Even if I restart or force quit and reopen it, it still happens. It only stops when I finally delete the font file. Why is this? Does the Glyphs not support it, or is there something else I need to know?

What version of Glyphs do you have?

Can you try to start without plugins. Hold down the Option + Shift key when you start Glyphs.

If that doesn’t work without plugins, please send me one of the files.

Yah, when I disable plugins, it is OK. So, what kind of plugin should I remove?

Please disable the first half of all plugins and check if the problem persists. If the issue remains, the problematic plugin is likely still active. If the issue is resolved, re-enable the first half and disable the other half.  
Repeat this process, progressively narrowing down your selection, until you identify the specific plugin or plugins causing the issue.

Thanks, After removing all plugins and scripts and re-adding a few, the issue is now resolved.

It would have been good if you could have narrowed it down so that we can fix that script. But good that it is working now.
