Please take a screen shot of this and send it to icomancer_support@lavasoftworks.com so we can figure out how to fix it.

This error occurred while using the content manager view and clicking on newly created folders in my icon collection section. It reoccurred every time I tried to click on a folder I had created during the session.

After completely closing all icomancer windows and reopening the program, the problem has not occurred again (yet anyhow...}

Your post was really helpful, because as in this case, knowing if an app restart fixes the issue is critical!

Thank you very much for the report!
I'll ASAP dig in the code to see where the problem lies.
