I have a Windows desktop MDI application, which sometimes throws an unhandled exception when a specific form is closed. Sometimes, not always. As far as I can tell with testing, it only errors when many other forms are open at the same time = the program is using a lot of memory.
Below is the error, I have done a lot of searching and reading, and cannot come up with a solution. If anyone can help I would greatly appreciate it.
